I'm going to a new high school and know Absolutely no one?

Hey! I'm also going to a new high school next year! The best thing to do on your first day would be to see who's in your classes. If you have someone who's in more than one of your classes, maybe introduce yourself then. Don't make the introduction too 'forced' though... you may come across a little weird. The best information I can give you is to be yourself, and just be friendly. Joining a club is a good way to know people with common interests, so that's a good idea too. For lunch time, find a table that has people that appear to be friendly, and welcoming. I'm sure you won't be the only one who's new there. If you don't find a table, maybe look for someone who seems new too. That's a great start. Good luck for the best! :)

if you're new, it's very likely that people will go near you to see if they like you. Just be yourself and don't try too hard to fit in. If people don't come to you, go to people.

oh well. its life and what you do is tell them your name and ask them if you can sit there and talk to them.
