IGNORED!

I'm at school rn, and idk why but some of my friends are just ignoring me. Idk why, but I'm trying to be really nice like always, but say when I said Hi to my friend, I got the driest response! and its not just one friend, its A LOT of them! they don't even acknowledge me! And not to mention, my friend purposely spilled my ramen and it fell onto me, I didn't even get a sorry. No to mention, its so cold and I have to be in my P.E clothes. Everything's going bad today T_T
