I don't like other people using my electronics. It feels like sharing my underwear.

And don't get me started about how a few of my friends choose to use their Facebook status updates... Ugh. "I'm tired," "I'm going to work," "I'm home from work!" "I'm having lunch with a friend." Or, the worst, when they put something vague that they clearly should put more detail on like my friend who once put "Just got back from the hospital. Exhausted. Goodnight!" WTF!?!
