Yesterday, I was feeling kinda down when I came home from work, but my boys were there, as always, to cheer me up. I've noticed, however, that each boy has his own way of expressing affection to us humans.
Arthur likes to play games; he'll turn his head, look at me from across the room, and meow for me to follow him. I'll usually end up following him into the kitchen where he'll rub my feet and expect a belly rub in return. Sometimes he'll go so wild that he'll grab my ankle and try to pull my toes into his mouth. This is very sweet, affectionate behavior, IMHO, but I've got to follow him around and play by his rules.
Beowulf, on the other hand, has a great knack for knowing when you need him. If you're feeling depressed or ill or just tired, he'll come sit next to you or lie down on your legs. He's a healer. Feeling the vibration of his purr would be enough to make anyone feel better.
