Just because I get mad doesn't make me a child. It doesn't mean I should go back to eighth grade, nor does it mean that I always act like a child. You know how passive I am.
Just because I scream and cry when I do have meltdown doesn't make me an idiot. Yes, I do contradict myself sometimes when arguing. Get over it.
Just because I've made past mistakes doesn't make them relevant to the conversation. (However, I'm guilty as charged, though. I've brought up your past mistakes, as well.)
Just because I'm arguing with someone else doesn't make it your business. You get mad if I ask you something and you accuse me of butting into your business, yet you push yourself into an argument when it has nothing to do with you. Hypocrite.
Just because I'm a girl doesn't mean I'm the typical teenage girl stereotype who cries constantly and is seemingly on their period 24/7. PMS is indeed a bitch, but it doesn't control my life, contrary to your belief.

If you don't want me to "get up all in your face", then drop the conversation and be the more "mature" person you claim to be and walk away.
...
You know, now that I think about it, you really aren't as mature as you build yourself up to be. I mean, if you're going to yell at me for not dropping a conversation, then please, for the love of God, practice what you preach. You look awfully foolish when you're yelling at me to drop an argument, yet you refuse to drop ours. How lovely is that.

Why do you make fun of/ridicule/criticize me for momentary bursts of immaturity. Everyone has shitty days. I don't go out of my way to make your day bad, or even attempt to, so why do you for me?
