On a Crowded Bus

I am a senior high student who has to commute from home to school every day. It is always an ordeal for me to try to get on a crowded bus. I am often squeezed so hard that I can't breathe.
Once I felt someone pushing me very hard, and then he touched my rear. I couldn't turn around to see who did it because I was sandwiched between two tall men. I was so angry that when the bus arrived at my school, I clenched my fists and elbowed my way through the crowd and got off. Then, to my dismay, I found that my purse had been stolen from my school bag.
