(Post translated from russian)

I (age 13) have a friend, lisa (age 14). lisa is usually nice, but she has mood swings and anger issues.

these mood swings usually happen in sports, but not just sports.

lisa thinks she is better than everyone else and is not responsible for her actions/mistakes.

lisa doesn’t hit the volleyball over the net. instead she hits it behind her, but blames me for it because “i didn’t catch it”. she also expects people to do things for her so she can make fun of them.

She has made me cry a few times and yelled at me, insulting me and stuff, but only in sports. otherwise she’s mostly kind.

she often takes girls very seriously and won’t laugh at their jokes, but will laugh at similar jokes from boys. she often says “ahahahahahaha! you’re so funny!” whenever a boy says something.

I just find it weird, but my friend said: “she’s kind of like ‘pick me’”.

lisa often says all the girls are mean to her, so i sympathize with her.

lisa is serious and bossy and likes to tell me what to do (not rude).

is this bad ? should i try to help and how can i help ? why does my friend say lisa is being a “pick-me” ?
