Establish and enforce boundaries.

My mom is the worst for one-upping. If you have a paper cut, she has arthritis in her spine. She’d also one-up with other peoples accomplishments- if you got 100%, someone else she knew got 105% with bonus marks. I went through childhood feeling like I wasn’t allowed to be hungry, cold, tired, scared, hurt, happy or proud of my self.

Now we barely talk. On the occasions that we do, I leave when she tries to one-up.
