I hate the people who call again and again thinking they must have just hit the wrong number on accident.... But nope, it really IS a wrong number. After the first time someone calls, I just let the voicemail get it, cause I figure once they hear a message with my name on it, they'll understand.
The area code on my cell is different from the one where I live, so whenever I see a Dallas number that I don't know, I can be pretty sure it's a wrong number.
