Dude, It's Called A Library
I exit the library as two teenagers, possibly college freshmen, are about to enter it. One is on his cell phone and as he looks up at the building, he says to the person on the other end, "Hey dude, I have to go, we're going to go into the thing."

haha, at least he ended the phone call before entering the "thing"! i loathe cell phones. that could be an exaggeration, or i may just loathe people who don't practice proper cell phone etiquette and continue conversations wherever they go, with no consideration for inappropriate environments.
Cell phones are fine, but inconsiderate use bothers me too. Sometimes people seem to treat the phone as a free pass to be rude.
