hot and lazy

It was said that my grandfater could pick up a fly and pet it. "Why, oh why, must the fly die?" he'd say, before slowly squeezing the life out of it. He could spend a whole afternoon like that apparently, hot and lazy, squeezing the life out of flies. Odd, when you think about it. Odd even when you don't think about it but if you don't think about it you probably won't notice, etc.
