Diane: Sam?
Sam: Hey, boy, what a coincidence! Just donated a pint of blood. The volunteer will be back. Just have a seat here and... Hey, bless your heart for giving, really...
Diane: I know why you're here. As luck would have it, a couple of nurses stopped by the bar. They had your fingerprints all over them.
Sam: I see. In that case, you don't mind if I sit down, do you?
Diane: From this angle, it's preferable.
