If you really thought about it, isn't this just you blaming them instead of you? If you were the right guy in the right state and presence and presented yourself well, would she still be stuck up?

I think whenever you think a girl is stuck up, you're just holding yourself back from improving the quality of girls you can achieve. What girl that's stuck up isn't extremely attractive to you?

I just noticed myself looking at a girl I opened today as stuck up, then I realized this. Don't blame her, blame your own mediocrity and fucking improve. ;)
