This reminds me of myself, a few years back. To think you're in the right place until the day you meet new people. "They're not real friends, they're going to ditch you once they receive what they want", your old friends would tell you. Your old friends, they're good people. Straight A students. Does their homework, goes to school, never talks back to their parents, goody two shoes. But they're wrong. I mean we don't really know anyone until we know them and we don't really know how anyone really is inside as in what they think of you, until the day you're no longer hanging around with them.
You're gonna find it a bit awkward at first, in a new crowd of people. They don't do things the way your old friends would. You're stuck in between. Wanting to fit in, thinking you don't. If you were lucky enough, the way I was, you will soon feel more at home with them than you ever did with those before them. They accept you for who you are, we're all different individuals. They don't expect you to act or stay a certain way. It wasn't like they dragged hell with them with every step they took. They opened my mind to a lot of things, mostly good but some couldn't take that.
Your old friends, they've been talking shit about you since the day you decided to walk out on them. They've been looking down on you like you were freely deciding to throw your life away. When all you did was have fun a different way.
