Fun, fun, fun.
My husband and I are exact opposites when it comes to our general philosophy of life. He is an organized, steady, no nonsense kind of guy who keeps me always headed in the right direction.
I, on the other hand, tend to.... wander. If there is the slightest potential for fun in a situation, I will head that direction.
I'm not sure when it started, but somewhere in our 23 years of marriage, we began a "good bye" routine.
We both say "Goodbye" and "I love you", but the then the script changes.
"Have fun", I say.
Be good, he says.
And we always take our own advice. :)
