What is the most important thing for your children to consider before marriage?
DH and I have two pieces of advice we hope our boys will take (in many years, since the oldest is only 12).
1. Marry your best friend.
2. Never, ever marry someone you haven't shared a bathroom with. Yes, this means live together before marrying. You don't truly know someone until you've lived in the same space with them.
So, what are your 'learned from experience' bits of wisdom?
