A childhood belief about teachers

when i was in elementry school, me and my friends would go to the main hall for assembly.
but all the time the principal was talking we was looking at the air vent above him. now, im the air vent must have been two slits in the brick behind letting in sunlight, but as the rest of the vent was dark, it looked just like a pair of eyes.
we were petrified for years that one day we would go to school and the "eyes" would come out and get us. we spend every day trying to think of what terrible monster the eyes could have belonged to, but noone dared to have a look on their own.

as you can imagine, no teacher believed us.
they probably knew and was hiding the secret from us. well, they didnt want our advice, so let 'em be eaten! ]:) teehee :)
