After spending several hours chatting someone up online, person A asks for person B's phone number. Person B plays hard to get and indicates that person A just might be lucky enough to get the phone number so person A persists with hopes that person B will eventually give in. Person A SHOULD just give up because Person B is just playing hard to get and who has time for that?

Sam: Dave, ya know I think you're superfly and would enjoy having a chat on the phone, seeing how we've hit it off on the computer for about 12 hours now.
Dave: Um no, I'm just going to tease you for ages before you finally show zero interest in me. At that point, I might give you my number just to see if you still want it.
Sam: Why ya gotta be like that, you Digit Blocker.
