My friend is all like "I can draw so good!!!" because she got a new How To Draw book. And then shes like "I can draw this, and this, and this and you can't". So I was responding with mmhmm and ok. So she said "I don't want to make you mad so I'll just hang up." well, too late, I'm already shaking with anger... Is This Normal?

I only watched a few episodes, and it's flipping awesome.
You could have got her off the phone, and see if she even telling the truth.
Don't let those types of people get to you.
She might have self-esteem issues, perhaps she's trying to boost her confidence?...
why was she your friend again?
Go critisize her grammar, because you obivously are just as childish as she is and must stoop to her level
