You just have to say it man...

All the flirting and smiling that has been going on between you and another person is adding up to some real tension...

but the catch is, who is going to act on it first...???

This is a real problem! And you will have to deal with this very real problem in real time...

There is no point in hesitating, because why would you want to...?

The possibility for rejection is always there, but you can be reasonably certain that right now you are getting the green light!
