My friend and I were playing a game called killing floor 2. You fight waves of zombies then there is a boss at the end. Everyone died from the boss and I was the the only one left and had to fight the boss alone. I almost killed her but made a mistake and ran into a railing so she cornered me and killed me. My friend was like “ha! Moron…” it kinda got my blood boiling. Usually when she’s joking around, she says just kidding but she didn’t this time. She also calls dummy a lot when I make simple mistakes.
you can be as sensitive as you please. What would happen if you gave up all the friends who called you names? Would you have enough left to enjoy life with?
Alternatively, you could just tell her you don't like being called names; a good friend would stop.
