Irrational part of the brain: DUDE she totally is checking you out
Rational part of the brain: Um, she is most definitely not checking you out, don't do anything stupid!
Irrational part: No way man, she was totally eye flirting with you, quick she's leaving, make up an excuse to leave too so you can start up a funny conversation on the way out, your sense of humor is your strong point.
Rational part: Pretend like you don't see her and her friend pack up their things and walk away. It will save you embarrassment and pain.
Irrational: Ya, but then you'll end up an old man filled with regret waiting to die alone.
Rational: No you won't, thats just not normal. If you were going to have talked to her you would have had to have had a legitimate excuse, and you didn't and now she's gone anyways so don't fret it!
Irrational: maybe if you leave now, you'll accidentally bump into her and be able to strike up a friendly conversation. . .
Rational: well you better get going then, but it better be a legit conversation, not, "hey i like your sweater wanna go out tomorrow?"
Irrational: deal.
"Tim are you talking to yourself on your blog?"
That is not a fair question?
