How do I avoid being friends with the wrong people?

[DiNoOoOo]

During my freshmen year I could seem to find the right people to hang around with. They either smoked, got into trouble/fights, and/or constant drama. I want to avoid this since I spent all of my freshmen year being involved with drama, and fights with ex-friends. For an example this girl who I considered my friend was talking shit about my other friends and I didn’t like that so I told her that I didn’t like that she was talking down to my friends and I told her respectfully. She got made and began to argue with me and well we dont talk anymore. I’m a sophomore now and I want to avoid this.. it too fucking exhausting.

I keep most people, even most of my family at a safe distance. A safe distance. I keep it friendly and laugh, but I don't allow them to get too close to me as a person. If they show me they are actually good people, I'll spend more time with them and slowly let them in.
Remember. This world is full of people you'll like and dislike. Friends can be replaced, even the ones you get along with. The more time you spend with the good ones, the harder it is to replace them, but coming to that point can take a long time.

You will make mistakes. be selective as possible AND speak with your parents about it. They have already been down this road so they have experience !!
