My sister used to be really heavy. Upwards of 250, heavy. She came and stayed with me for a week, and we went bowling with a friend of mine. My friend brought a girl I've never met, who seemed rather.. snobbish. Granted, my friend and this chick were both ______/actresses, something I realize makes most chicks think they're hot shit.

Anyway, this unknown chick decided taking sneaky pictures of my sister while we were bowling was somehow a great idea, even knowing I was sitting behind her. I watched her post them on instagram, and saw red.

The phrase gets thrown around a lot, but I'm the only one who gets to be mean to my sister and that would be crossing the line regardless. So a few minutes later when she asked me to take a picture of her and my friend, i instead deleted the picture she took and the one she posted on instagram. Gave the phone back and told her she could find her own ride home.

Few days later my friend found out what happened and apologized.

Tl;dr, dont make fun of people in front of their incredibly protective older sister.
