the windows in my office are tinted.
from the outside, you can't see in and are instead faced with your own reflection.
this means that occasionally, people forget that there is in fact someone on the other side who can see out. they'll wander by, picking their nose.. or stand right next to the window while having their smoke, and examine themselves in my window. my desk is situated directly on the other side of the glass. i stare at them glaringly, hoping they'll peer close enough to get past the reflectivity and suddenly realize what they're doing. ut hasn't happened yet.

amusingly enough- usually the only people who walk by are from the set of offices next door... who have the exact same windows.
