It makes no difference how old they are. I don't care if it was acceptable "back in the day." Don't touch anyone without their consent.
I saw this guy at a local community event. He’s probably in his 60s at least, and I’m in my mid-twenties. It was the first time we met and talked. He sidled up to me for some paperwork related to the event, and as he was explaining what I needed to write down, he started caressing my back and went up to my bare neck (so pretty high, because I was wearing a regular t-shirt). I froze and pretended everything was fine, but I felt so gross. In our first interaction, I don’t want to know how he acts once he gets more comfortable.
I cried when I got home. I wish my trauma response wasn’t to freeze and "let it happen". I’m neurodivergent and absolutely hate confrontation. I don’t know how to handle things like this, but it makes me easy prey, and I hate that about myself.
