Don’t worry Panda, it’s the Moth (guys) to the flame (loud girls) thing. There is no depth and the interaction is short lived.
I would dare say (as a guy) that quite girls are more interesting, and it is a guy’s job to get the girls interest. If you look too hard, you will not find anything, just relax. Sometimes you just need to blurt out what is on your mind, think of it as a conversation starter.
