What is the most tragic thing you've ever had to deal with

I got raped on a bus, I was about 7 years old. Not the definition everyone is accustomed to but it was an outrageous violation. The bus was crowded and I was with my mom just like every weekday morning she took me to school before she went to work herself. We were standing, a man put his penis on her back/butt, I didn't say anything and don't think I said anything when we got off the bus either, I did my best to forget about that day for a long time but I can't and I'm not too sure about that detail. There was a stain on the back of her dress. Fast forward at least 5 years, by chance I went grocery shopping with my parents one weekend midday and the guy from the bus was there too, alone and doing his grocery shopping. I didn't say anything.
