I like receiving wrong numbers, because, to me, there is no such thing thing as a wrong number. You may have called a different number than you intended to, but who am I to say it's wrong? I think it is embarrassing when someone tells you that you called the wrong person. So, I like to talk with caller and pretend to be whoever it is they think I am. Eventually, they realize I am not and they hang up on their own. That way, no one gets embarrassed.
