Ladies Do
Do Speak on the phone before you go out.
Talking on the phone gives a sense of security and comfort before you meet them in person. Hearing their voice for the first time can make or break it. You don't want to discover his bizarre high pitch for the first time at the dinner table and it's too late.
Do Not hesitate to ask your mutual friends about him.
When people ask me about guys from college, my hometown, or any of my mutuals, I'm generally able to steer them in the right direction. As a friend of theirs, I know if they're lying about their age, how old their photos are, and whether that's his Porsche or his daddy's.
