This piece is rather sad to me. Have you been feeling a little disconnected from the world, Jack?
"A thousand windows pass me by,"
I have no issue with this line. I rarely do with the first part of a poem, unless the author is Angelou.
"the majority lighted, allowing view of corridors,"
I'm with billy on "allowing"; It's a rather dry word. I cannot tell you how to remedy this, but I would like to see something that SHOWS the inside to be illuminated. Perhaps a more direct image?
"whitewashed walls and half-glimpsed doors."
Half-glimpsed doors is unique and interesting, not to mention dynamic. I feel as if I'm barely catching a view of these "doors", which is an image that gives this line a sense of motion. "Whitewashed" is okay, but I don't feel like it adds too much. I already pictured these walls as "whitewashed", so I'm not sure if you'd rather replace it with something a bit more surprising. Again, this is just my opinion, and the adjective isn't much of a problem. At least you're not saying "bright".
"The bus curls round them like wrapping paper"
I'm ambivalent about this line. It's unique, and a great, simple image. HOWEVER...When I picture wrapping paper being wrapped around an object, I visualize an item that starts out wrapped, and ends completely concealed by it. I guess you could say that the bus wrapped it in its "path", but, you know what I'm getting at. It's probably just me; I'm fighting off the flu and feel worse than a woman at a monastery.
"and in the dark they become eyes"
Solid.
"I wonder how many students live there,
if any of them have caught sight of me."
Bringing the poem to a good close.
I liked it. Makes me feel a bit lonely

Good work.
