It's true what they say.
Your friendships - loyalty, trust, honesty, love - it all gets put to the test once you enter high school. And you know what, sometimes, those friendships end up fading into the background because there isn't enough effort put into it and there isn't enough communication. There just isn't enough. There isn't enough to hold it together, like how it was held together before.
High school pushes you to the limit when it comes to friends. It teaches you lessons after it gives you the test. And it's true when they say that you find out who your true, real friends are in high school, because this is the reality check. High school is the slap in the face.
You realize that people change, sometimes for the worse, and that you might not be able to do anything about it. You realize that people won't stay, even when they promised you that they'd always be there for you. You realize that people will lie to your face and lie behind your back, and the two different sides of them will finally show. You realize that the people you thought were your best friends really aren't. You realize that things fade and end when they do for a reason, and sometimes, letting go is the hardest thing to do. But sometimes, letting go and letting change happen is the only thing saving your life.
Friendships don't last. That's one thing I learned in high school - and I'm only three weeks in.
