Everybody judges other parents. Everyone.
The thing is, we're humans, and we all like to do things our way. And then we see people doing things differently than us, or things we don't think are the right way of doing things, and we judge. Without thinking of the fact that the person your judging probably would have something to say about what your doing too.

I judge the mothers in the shopping centre screaming at their kids, and ripping them by the arms towards them and smacking the crap out of them, right there in the middle of target.
Only cause i think it could of been dealt with in a less of a "COME HERE YOU LITTLE UNHOLY SPAWN OF SATAN!!!" fashion. (although my brother has a tendancy to make me think he's the antichrist at times. ahh little 4yr old boys)

Don't feel to bad about judging, it's natural. As long as your not doing it 24/7.
