I love callerID.
If I get a number that I don't recognize, I'll call them back. Usually it's a friend with a cell phone, or a friend of my roommate's.
Funny too, because if it's someone trying to sell me something, I have a thing on my answering service that tells people that I don't accept calls from telemarketers. Yet they still call...dumbasses.
I did make the mistake once of yelling at the person that called, after the same person called like 5 times in 10 minutes. It turned out to be my dad. He wasn't too happy, until I explained it to him.
