I was on the 75 bus coming home from school at around 7pm but due to it being winter it was quite dark and quiet. I had the whole bus to myself until an older man came on and sat right next to me. I thought it was weird but didn’t say anything. I had my headphones in and just stared out the window. After a few stops he decided to put his hand on my thigh. I had my school uniform on which included a skirt. I didn’t know what to say or do and there was no one else on the bus the entire way home. When it got to my stop he didn’t move out of the way for me to get out even though I had asked him, so I ended up having to climb over him. My skirt was quite short at the time and i didn’t wear shorts underneath. When i walked off the bus he gave me a creepy smile and wave and I just tried to ignore it. a few times after I would still see him get on the same bus and smile at me but he’d never come over to me when there was someone else on it.
