My father-in-law is thinking about buying a GSP.

The other day, I heard a story...
A couple invited some friends to a restaurant. A friend called and asked for the address, so he could map it out from his GPS. Everybody decided to wait for the other friend.
Forty five minutes later...they decided to go in and start eating.
They forgot about the friend when he called an hour after they got started.
"I got so lost!"
"Oh, really? But you're here, right?"
"No, I don't think I'll go anymore..."

Maybe I'll have to tell my father-in-law that buying a GPS is not a very good idea after all...
