Don't take it to seriously. It usually just means he wants to get to know you and isn't sure where to start and is hoping you will get the conversation rolling.
If this is not the case, then IMO run. and its because he is needy, insecure, ect.ect... you know all the things that brought us here..
I could not disagre more. I prefer to get to know a gal before even agreeing to meet. There are many questions I like to have answers to first.
Granted - he could be a little less vague.
Start firing pointed questions at him and see what happens. If he is for real, he will respond in like kind.
