You look very nervous, Joe. Relax!

I can't. You know this is my first blind date. My heart is beating very quickly.

Then take a deep breath or go out to get some fresh air.

It's useless.

Actually you don't have to be so nervous. You look great today and that girl is very nice and easy-going.

Really?

Sure.

Maybe that girl is as nervous as me.

Well,maybe.
