Just interact with people. Every small thing counts, I made friends with one of the girls just by waving at her as she walked by me outside, she ended up going up to me and we had a whole conversation I wasn't expecting

For the kids I just asked them questions and listened to them

Also sharing, especially food, is a good way to get ppl to like you, when I'm eating a snack around ppl I always offer it to them bc it feels rude to eat in front of ppl without offering to share TvT

Just don't be painfully awkward and shy bc everyone will think your weird and antisocial, ask ppl small questions when the opportunity comes up, even if it doesn't become a whole convo it WILL make ppl more comfortable with you

Not everyone is gonna wana be your friend but being friendly with everyone will help you find ppl who will! (This is rlly important especially if your like into weird stuff, bc ppl might think your weird and just not want to hang with u which is totally ok bc that just means it isnt meant to be but you shouldn't let that stop u from being social)

I've never really been the popular girl or anything but I'm trying to work on being more social and just doing that has helped me get a whole little friend group in less then a week:)

So in summary if you want friends be friendly lol, literally just talk to ppl and listen to them:P
