How do you expect yourself to be given a chance when you don't give others a chance? KARMA.
It's weird how we get 'turned off' by some people even without knowing them. Is this being mean or is it another natural sign? Maybe it's time to start giving chances. Everyone deserves a chance, whether it's relationship or friendship or whatever ship. Even if our character clashes, at least we have tried right? Otherwise, we may also be depriving ourselves of an opportunity to meet another friend, who knows, maybe best friend?! That'll be a big loss! :)
