How many of you say this when someone calls on the phone and asks for a stranger? I know I do. Instead of, "You have the wrong number", I always say, "I think you have the wrong number."
My Mom, Dad and sister were having dinner. My Mom's cellphone rings. The caller asks for "Lucille". My Mom replies, "Lucille? I think you have the wrong number." The caller apologizes and hangs up. My Dad (who I swear sounds more and more like Victor Meldrew every day) say, "You THINK you have the wrong number? Lemme check.... He gets up from the table and starts calling all over the house, "LUCILLE! Are you here? YO! LUCILLE!" My Mom and sis are crying they are laughing so hard. My Dad comes back and says, "What? Are there so many people living in this house now you can't keep track of them all?!"
Anyway, it did get me thinking as to WHY I say, "I *think* you have the wrong number", when in fact I'm *positive* they do!
