After being left alone all day Socrates is attention starved I think. He's finally settled down from a fit of insanity, running around, attacking, biting, and generally playing. Now he's switched to "love on me" mode. He wants to be right on me, in my face, purring and wanting to be petted.
While this isn't abnormal for him, his persistence is. I'll pet him a bit and then lay him down on the couch beside me and he'll immediately jump right back up on me. I put him down and he jumps right back. We did this so many times I just couldn't stop laughing. Kinda like a furry yo-yo.
He finally wore himself out and fell asleep laying on the couch using my leg for a pillow.
Ah well, after a really tough day he managed to make me laugh for a while.
