We told our youngest that her siblings and her are all 200% stubborn.

She argued. No if you and mum are 100% stubborn and I’m made up of the both of you then I’m only 100% stubborn. It’s because I’m 50% of you and 50% of mum.

Hmmm I think she’d make a very good lawyer. She’s been like this ever since she was young. Always arguing her case.
