Bus Ride Nightmare

I was going back home from school in the bus. My school uniform was a navy blue sweater with a white polo t shirt underneath and short black skirt with black tights. I was maybe around 15-16 then and sat in the back of the bus. A man with his son walk inside and sit a few seats ahead of me, on the opposit side of the bus. I notice him glance back at me a couple of times and I start feeling uncomfortable. He turned around again, bending his back from his seat to look at my legs. In that moment I just felt fear, helplessness and confusion because nothing like this had ever happened before. I couldn’t speak, think, nothing. When my stop finally came I was so scared I left the bus from the end doors so I wouldn’t have to cross by him. When I got off and the bus started moving ahead, I saw this man look at me, wave, and smirk at me. I wanted to cry, I still remember feeling so scared that he’d follow me or smtg. I just wanted to cry. I never told my family about this because I just didn’t feel like I could. But I genuinely cried as I walked back home. Now when I think back about it, I feel so bad for the little boy, who I’m guessing was his son. He was so clueless and happy, with a kfc bucket in his hand all that time not knowing his dad was a pedophile.
