I was incredibly drunk and talking to a friend a few days ago. I was unfortunately that person. I asked her for a picture of herself. I've done this one other time to her. When I came to, I felt incredibly shitty. It still bothers me that my mind went there, but I was drunk and it's in the past. Luckily she's one of the most amazing people I've never met and she handled it with poise and that was the end of that.
With all that being said, you, as a grown ass adult, have the right to tell anyone to fuck right off for any reason. Especially if that reason is that they make you feel bad about yourself. Don't let other assholes hold you back.
Chin up, chest out, and keep moving forward.
