Story about one of my friends, and what happened.

Problem

The next day someone had said that she had taken her backpack, which my friend was being polite and declining that she took it, when she didn't even do it, The girl said a stupid, Stupid excuse, "She stole my backpack so she can do what ever she wanted with it!" My friend started to feel like a leftover 10 year old chicken, My friend then said, "I-I swear! I-I didn't take anything f-from you!" I then saw this and said, "Hey! What are you doing to my friend?" The girl then laughed and said, "Hah, your friend? She's a thief! And she stole my backpack!" This immediately pissed me off, "Why are you being so judgemental?" The girl's other friend tried to smack me in my face but ended up being knocked out, "If your only doing this because she's Bisexual, then you can go look at yourself in the mirror!" She automatically ran off and was scared she was next. My friend was scared for a while but after a few she was ok again, then she thanked me, and she rarely gets bullied now, but I hope this teaches you that You can't just bully someone just by their sexuality, it is rude and disrespectful! And you might regret it!
