I can't speak for everyone, but dialing the wrong number happens to me a bit. Usually when I dial a wrong number I can tell when I'm not talking to who I mean to call. Orr if I can't tell right at first, I figure it out pretty quickly.
Anyway, some guy named Phil called today...
Me: Hi? Who is this?
Phil: It's me! Phil.
Me: Ok... (long pause) I don't think I know a Phil
Phil: THIS IS PHIL ANDERSON SPEAKING TO LAUREN... AM I RIGHT?
Me: No. This is CARLI TALKING TO PHIL AND I DON'T KNOW YOU!
Phil: Then I have the wrong number then?!
Sheesh. Phil was rude. I hope he doesn't call again.
