Why do some people think they're perfect??

Okay I have to get this off my chest because it's been driving me INSANE lately.

Why is it that some people are so quick to pint out everyone else's mistakes, but completely ignore their own?? Like, they'll act like the behavior police, judging everyone left and right, but the second they mess up?? Silence. Crickets. Not even a ''my bad.'' 

I know someone like this and it's actually exhausting. If you shoe up late - '' You're so irresponsible.'' But THEY do it?? Suddenly it's ''I had a rough day'' or ''I'm just like that, lol.'' NO.  That's NOT how it works. You don't get to call people out and then pretend like you've never done anything wrong.

It's just so hypocritical. Like, don't throw a whole tantrum about someone's attitude when you literally snap at people over nothing every other day.

We're all human. We all mess up. But if you're gonna call others out, at least have the maturity to reflect on your own actions too. You can't live life without a mirror that only works when it's pointed at everyone else.

Anyway, just had to rant because people like that make everything harder than it needs to be. Fix yourself before you go trying to fix everyone else.
