What should my topic be? I have to write an argumentative paper on something that involves marriage and family?

It cannot be about gay marriage or divorce. It has to have two sides that can be argued. I’m having trouble deciding. Your help would be appreciated.

What age is appropriate to allow a daughter to date?
A stay-at-home dad?
A family has to move out of state for parent’s work but it’s their child’s senior year of high school…what to do?

I hope I helped :-)
