Heather has been my friend since we were in 3rd grade. We had the same teachers most years. We did cheer together. We stayed close in middle school, but we had different classes so I didn’t see her as much in school, but we still got together after school and on weekends.  We both made new friends. A few weeks ago, heather passed me in the hallway at school and I waved to her. She looked away. The next day I saw her on the bus and went up to her but she moved away. After that, she never talked to me again. I have no idea why.
