I'll even say something like, 'Alright, just so there's no confusion, you know I'm going to call you up when I deem fit and ask you out, right?' Then I'll be all pleased on confident with myself and not even try to follow through. I don't know what to do with them even if I did get around to asking them to go on a date with me.

I'm thinking something along the lines of:

Hey, it's Mars from the bus, let's go out for lunch tomorrow.

How's that? General advice thread on how to follow-up? First-date ideas?
