I'm one of those horrific people that drive the rest of the population crazy: I'm a morning person.
I wake up and it's instant. I get going--worse, no coffee, since I'm allergic to caffiene--and do what needs to be done. I wind down somewhere around 1pm, most likely because I forgot to eat, then I'm at it again until 8. I sit down, relax once the kid is in bed and eat with hubby. I occasionally get to read. Or we watch tv or a movie. Or we work. We're up anywhere from 9 to Midnight. Then we're back up at 6:30, 7am.
My sister, Pet, who is visiting because I'm at the point where I can only get up a few times a day without need for some pain killers (which I don't have), however, is a night person. She likes to stay up until 3 or 4 am...and sleep until 12 or 1pm.
So, since I can't move a lot, I do get the utter enjoyment of waking her up with cheerfulness at 7 in the morning. Picture Wednesday at Summer Camp, lol, and you've got Pet at my house.
