I'll put in a vote for the Big O, as well as falling asleep and knowing you can sleep as late as you want to the next morning.
Also, I LOVE when it's about 11 at night, my house is clean, my husband, kids and dogs are all upstairs asleep and I am curled up on the couch in my fuzzy robe with a cup of tea and a good book. It just feels good to relax by myself for a bit knowing that the people I love most in the world are safe and everything is, for the moment, in order.
