I wish we were who we were before it happened

Sometimes, will you have a feeling that, towards certain people, you rather you don't really get to know them? Really, some people just not really as good as what you thought they are, until you really get to know them... But true enough, in this real world, we'll always get to know this kind of people, don't we? Anyway, we cannot choose who we're going to meet, but we can choose who we want to be our friends right?

I wish we were who we were before it happened, for those who I rather don't really got to know them...
