Correção de texto: Strife

I have seen some fights at school many times, I remember that conflicts among pupils were quite normal. I have never joined them though. Now I do not study with teenagers anymore, but with young people, and now it seems to be even worse. For example, my friend made out with one guy at a party, but she does not want anything with him anymore, and he keeps insisting and following her and threatening her life, if she does not date him he said that he is going to kill her. Another example is an another friend of mine who made out with a guy as well, then that dude made up with his ex-girlfriend, but while he was meeting my friend, his ex knew that they were going out. Now that they are together again, they have gone to the university to settle accounts with my friend, he wanted my friend to lie that she is the one who searched for him, and that is not true, his girlfriend threatened her life and said that she is going to bother her life forever and even to kill her someday. There are so many loonies and can not hold their feelings.


Obs: I would like to the people/person who read/s this, tell me which grammar points I must study, thank you guys.
