Secret rivalry

Does anyone have that one family member that they secretly want to do better than? It sounds childish but I think deep down we all do. I like to try and do better than my cousin because she's always thought she's better than my side of the family. Like when I see a picture of her I think to myself...ah I'm skinnier than her! 😂😂😂 Nothing vindictive and I don't believe it's jealousy. It's the big headed egotistical attitude from the past that's probably made me like this towards her.

So is there a family member that you like to think you can do better than?
