Mr Blottisham had been standing at the Senior Common Room window for several minutes.
Professor Quillibrace noticed.
"Are you expecting something?"
"No."
"Then may I ask what you are doing?"
"Looking."
Quillibrace glanced towards the window.
"An activity of increasing rarity."
"Is it?"
"Among those who have discovered screens."
Blottisham ignored this.
"I have always found windows rather disappointing."
"Disappointing?"
"Yes."
"In what way?"
"They do remarkably little."
"Do they?"
"They do not transport us."
"True."
"They do not cook."
"An important omission."
"They do not provide shelter."
"They contribute to shelter."
"By leaving a hole in the wall."
Quillibrace considered this.
"A rather unusual way of describing a window."
"But accurate."
"Only if one assumes the wall was the achievement."
Blottisham looked puzzled.
"What else would it be?"
Miss Elowen Stray looked up from her book.
"Perhaps the connection."
"Between what?"
"The room and the world."
Blottisham turned back towards the glass.
"But the room exists perfectly well without the world."
"Does it?"
"Of course."
"The walls remain."
"Yes."
"The roof remains."
"Yes."
"The furniture remains."
"Yes."
"And yet something changes."
"What?"
Miss Stray smiled.
"The room stops listening."
Blottisham looked uncertain.
"Rooms listen?"
"Perhaps not literally."
"That is reassuring."
"But they can become closed."
"Closed?"
"Cut off."
Quillibrace nodded.
"A room without windows is not merely darker."
"It is more separate."
Blottisham looked through the glass at the college gardens.
"So the window gives us light."
"That is one of its functions."
"Air?"
"Another."
"Then what is the mysterious third thing?"
"Perspective."
Blottisham considered this.
"That sounds like something people put on motivational posters."
"It is nevertheless useful."
Miss Stray stood beside him.
"Notice what happens when you stand here."
"What?"
"You remain exactly where you are."
"Yes."
"The garden remains exactly where it is."
"Yes."
"And yet you have entered a relationship with it."
Blottisham looked amused.
"Through a pane of glass?"
"Precisely."
"The window performs no journey."
"No."
"It simply makes one unnecessary."
Quillibrace smiled.
"A remarkable achievement."
Blottisham looked at the glass.
"I suppose that is why people like views."
"Yes."
"Not because they can reach them."
"Exactly."
"But because they can see them."
Miss Stray nodded.
"Seeing is sometimes its own form of movement."
Blottisham looked thoughtful.
"A window is rather like a painting, then."
"Similar."
"Both show us something."
"Yes."
"But different."
"Very."
"How?"
"The painting asks us to look at it."
"And the window?"
"To look through it."
Quillibrace added,
"The window succeeds by becoming unnoticed."
Blottisham frowned.
"That seems like a strange measure of success."
"Many excellent tools have this quality."
"A good bridge disappears beneath the journey."
"A good letter disappears behind the person who wrote it."
"A good window disappears behind the view."
Miss Stray looked outside.
"The invisible machine works best when we stop noticing the machine."
Blottisham nodded slowly.
"Although every window also chooses what we see."
"Ah."
"That sounds important."
"It is."
"Because a window reveals."
"Yes."
"But it also hides."
"Exactly."
Blottisham moved slightly to one side.
"The view changed."
"Did the garden change?"
"No."
"Only your position."
"So the frame matters."
"Very much."
Quillibrace returned to his chair.
"Every understanding begins with a frame."
"Every understanding?"
"Scientists frame experiments."
"Historians frame events."
"Artists frame scenes."
"Teachers frame questions."
Miss Stray smiled.
"We never see everything."
"That sounds like a limitation."
"It is."
"And yet?"
"It is also how anything becomes visible."
Blottisham looked surprised.
"Explain."
"If we tried to take in everything at once, we would see nothing clearly."
"Like trying to read every book in the library simultaneously."
"Precisely."
"Or listen to every conversation in this room at once."
Quillibrace glanced around.
"An excellent way to achieve both confusion and unpopularity."
Blottisham laughed.
"I suppose children understand windows better than adults."
"How so?"
"They watch storms through them."
"Yes."
"Count cars."
"Yes."
"Wait for someone to come home."
Miss Stray nodded.
"The window becomes a companion."
"It does not demand action."
"It invites attention."
Blottisham looked out again.
"Perhaps we have forgotten how much looking matters."
"Perhaps."
"We always want something to happen."
"Yes."
"But sometimes seeing is enough."
A pause followed.
Then Blottisham said,
"There is something strange about windows."
"Strange?"
"They work both ways."
Quillibrace nodded.
"Indeed."
"When I look out, I see the world."
"And?"
"The world can look back."
Miss Stray smiled.
"The opening that enlarges our view also places us within someone else's."
"So perspective is never entirely private."
"No."
"It always connects."
"Exactly."
Blottisham sat down.
"I think I understand why people want windows in unfamiliar places."
"Do you?"
"Hotel rooms."
"Yes."
"Trains."
"Yes."
"Airplanes."
"Yes."
"We want proof that our little corner has not become the whole world."
Quillibrace nodded.
"A very good observation."
The afternoon light shifted across the floor.
For a while none of them spoke.
They simply looked.
Eventually Blottisham said,
"I began by thinking a window was a hole in a wall."
"And now?"
"I think it is the part of the wall that remembers there is a world outside."
Quillibrace smiled.
"A surprisingly generous description."
Miss Stray returned to her book.
"Perhaps that is why we seek windows."
"Why?"
"Because every shelter needs a reminder that it is not a prison."
