G'morning.

I just joined this group looking for some advice. My ex-wife & I have
joint custody of my teenage daughter who just turned 18 this past
week. Sometime last fall, she broke curfew at my place & I punished
her accordingly. Now she's broken curfew at her mom's. My ex-wife
wants to punish my daughter & wishes that I 'match' the same
punishment at my place. Basically, to be on the same page. I disagree.
I don't have as many problems with my daughter as does my ex-wife.

Advice?

She's 18. She shouldn't have a curfew.
