I'm think I might post about MBM today, and maybe talk about friendships and frenemies. This girl, MBM, has been bullying me and my friends for over a year now, but still pretends that we are all each other's best friends! Last year, she told her family that my one of my friends (let's call her hamster) killed all of her hamsters (she had a hamster, it passed away, she got another hamster, it passed away etc. the shop she got them from had something wrong with their pets), she called me a bitch just because I didn't tell her my best friend's biggest secret in the whole wide world! She also made hamster 2.0 (another friend) cry the other day DURING OUR GEOGRAPHY LESSON! I know, I know, "Why don't you just stay away from her? It seems like she's really mean?". But, if we don't try to be her friend, she has no one. And, despite the fact she's making me and my friends upset and stressed, I can't do that to someone and then leave them with no friends. It's my own little moral dilemma. AND I DO NOT LIKE IT! It sucks having this sort of things happen in your life, because it's almost like a rhetorical question, it may never be answered. Do any of you have any troubles like this? Any friends you think you might have grown out of? Let me know in the comments below!

*UPDATE UPDATE UPDATE*
She is now trying to become friends with hamster again! Goodness, teenagers are difficult. I feel bad for our parents!
