I'm absolutely disgusted 🤢

Today I was at Wal-Mart getting a few things for dinner and a man came up behind and slapped my ass. My natural instinct was to turn and slap him in the face. As soon as I did, he stood there, and he looked shocked! He said " uh, what the fuck was that For?" I said "for slapping my ass" and he said "I slapped it because I thought it looked nice!!?" Acting like he's offended. I told him to fuck off and walked away. I felt embarrassed and violated and I didn't know what to do or what to say, so I just left. Looking back I wish I had said more but I was in a shock. He made me feel like slapping him was wrong, like he was the victim. I cried in my car for about 10 minutes, then made my way home. I don't feel like talking about with anyone. So I thought I'd hop on here so I can talk about it anonymously. I just had to get it off my chest. 😕
