The first incident was when i greeted someone i met in the cafateria the previous semester yesterday in the hallway which was only my first time speaking to them this semester. She smiled after i greeted her and appeared to be confused. The second incident i had on the in the hallway while transitioning to gym when i shook one of my friends hand. He didn't just shake my hand he grabbed my hand and yanked my arm forcefully and walked away with a straight face. I had gym class which is my favorite and easiest class yesterday. There was nothing to do outside of playing basketball and sitting down. I wanted to play basketball yesterday and before they created teams i went over to join and one of them jokingly told one of them that i was going to be on his team. I stood in that area until they started the game and i was not chosen for either team. Some of the others who watched on the sidelines had next and i wasn't even chosen for next by anyone. I was close to the action but i was ignored intentionally. I waited during the second game after that one and the result was the same. I didn't get picked once again. I tried to shoot around with them before class ended but i got one shot attempt for the entire class period and that was before any game started. What i mean is that others have freedom from being forgotten by people who they met before,getting their arm yanked during a handshake,and from being ignored by everyone even though you're clearly in their presence.
