Look, I don't give a fuck how much you swear. I like to swear. My first ever writeup was cunt.
But I won't have you insulting my friend like that. That's right, when you say bad things about yourself that's MY FRIEND you're talking about, and I'm kinda loyal to my friends.
So hows about you have a bit of a think about it, and either you put some money in the Not Swear Jar, or you reframe that insult.
For example, instead of saying "I'm stupid", you could try saying "I got so many questions wrong on that test".
Instead of saying, "I'm ugly", you could say, "I don't feel attractive today".
If you are finding it hard to reframe it just right, I'm happy to help. That's what friends are for.
