What do you think

So I was walking in my neighborhood park and my neighbor (around 70) was walking too, he asked me if I wanted to join him in his walk so me being polite i said okay but just for a little because i have to jog. I know my dad and brother have had some conversations with him and I was just being polite. He asked me how was my jobs and stuff and I told him a little bit about what I was doing and then before I left he pats me on my shoulder which made me a little uncomfortable and then told me that I’m looking sexy. I felt so uncomfortable, so I told my mother about how weird that was and she said that I’m the weird one because I don’t have to be walking with anyone and that people have bad intentions to not say good morning or be polite anymore. I’m 20 and I find her perspective to be wrong I think I didn’t do anything wrong.
