There's this one girl at school who lies a lot to me. At first I didn't realize it because I considered us friends, but lately I've been catching her in many lies. I've tried confronting her and she denied the whole thing, but I'm seriously not sure anymore. I've realized that venting on Witty is now considered complaining, but I just really need some advice. So thanks for reading this if you have, and if you have any advice on what to do, can you please let me know?
