or you can be yourself because if you ever go out on a second date, you're going to have to put ALL that effort into being not yourself.. what is that listening joking around, something you're not used to?
and if this goes onto a long term relationship, you're fucked because she'll like you for the person you were trying to be and not the person you really are.
you'll soon get tired of pretending to be someone else

thats my perspective if i was the girl going out on the date with you.
