Learn the difference between "your" and "you're". Always use them in the correct manner. (This mistake drives your mother nuts and she will judge people who dont understand the difference. sorry 'bout that.)
Respect your parent's friends, and the parents of your friends. Call them Mr and Mrs or Ms until invited to do otherwise.
Recycle all that you can.
Understand that even the most in love couples will fight. If your parents are breaking up.. we promise you will be the first to know. Arguments, misunderstandings and disagreements are all part of any long term relationship.
Breaking up is hard to do.. but not as hard as living with someone you no longer love or respect.
The jury is out on staying together for the sake of the kids.
Vintage linen tea towels are lovely.
