My friends seem to always have a hell of a time getting a hold of me, regardless of the fact that I always (except, you know, when I don't have it....) have my phone turned on and check my email obsessively.
-sigh-
I absolutely hate the day of a seating change it's like they already know who I'm sitting by, their number, etc. Especially if I don't know the person who's phone, I'm being contacted with. . . . it's unnerving.
