the tired doesn't end

Billy picked me up this afternoon, and I spent the day with him and Charlotte. We had pizza and watched random TV, and I felt a migraine coming. Charlotte let me nap in her mother's room, with the new Sleep Number bed (my number, it seems, is 35). Then, we drove back to my home and Charlotte brought her Litter Maid and showed me how it works. It's running on batteries. The cats seem fine with it. Sometimes, however, they don't properly cover their mess, so I just scoop some litter on top, before the mechanism whirs and clicks and pushes the waste into the plastic receptacle. It is a cute thing, and it senses when the cats are finished. Charlotte's three cats had gotten too big for the Litter Maid, but my cats are small, and Jupiter has his own box in Jason's room.
Charlotte helped me clean up the living room. She and Billy left. I am watching random TV now, and this of course. I have no desire to go out, unless it is to get chocolate. Danny went with Steve and Dirk to Renn Faire. I cannot afford to go and I doubt I will find the time unless Adam has a weekend off, and even then I don't know. I think Jason went camping. I like being at home alone on a weekend; sometimes it can bore me, but that is why I have books, and the computer. I will be working on the book shortly; still Chapter 21, with a mild block. I'm so tired.
The migraine isn't going away, even with pills.
