I've decided, that the BEST feeling in the WORLD is that 9 minutes between when the alarm goes off and when you actually get out of bed. OK, so 18 minutes. If I'm lucky. But really, sleep is the BEST EVAH, and since while you are sleeping you can't know you are enjoying it, that time frame of starting to wake up, but still knowing you are sleeping, that is my favorite of all time. A close second is being woken up in the middle of a nap and getting to fall back asleep again. But this one is risky, because if you don't fall back asleep, then you are screwed.
I'm assuming its greatness is magnified by 1) having to get out of bed is one of the worst feelings, especially when it is cold and dark and 2) I have two youngsters WHO DO NOT LET ME SLEEP.
I know this will change someday, and I will have have to beg them to get out of bed. But who am I kidding, I will be sleeping in with them, so we will all be rushing to get out of the door together.
