When you open a pack of gum in class everyone wants to be your friend

Today I was in class and I had a pack of mint gum. Now mind you I NEVER take gum to class like this is the first time EVER. So I gave a piece to my friend E and she opened it at her class table. A girl at her table (S) saw her and asked her where she got it. E said she got it from me so S asked if she could have one. I opened my pack so I could give her one and Literally the WHOLE CLASS was asking me for a piece. The guy next to me was all like “I gave you 2 whole pieces last class!!” (He did not) so obviously I told him no. He kept annoying me about it and I was trying to put it away when he reached into my bag, grabbed it, and took 5 WHOLE PIECES. I can’t even. Then the teacher noticed and took my gum. Everyone was mad at him because nobody else who asked got gum. The worst part is the teacher didn’t even give my gum back.
