(Well, actually, he and Sis used to have fairly similar schedules, even allowing for the commute, but that's beside the point.)
Usually, when we invite him to a family event, he says "Well, I'm working, so I most likely won't be there," and doesn't show up. Today, though, when I called him on lunch break and asked him if he'd like to stop by after work for a movie, The Wall, with me, Sis, Neighbor, and Alan, he said he wouldn't be able to make it, and then elaborated. It seems that after work, he's tired and grouchy and really not fit human company. "Some other time," he said.
He sounded happy to talk to me. He sounded grouchy when his dad handed him the phone, but his voice warmed up and did almost the Evil Darkside thing at me, but not quite. I had to get off the phone before he wanted to stop talking.
I grinned the rest of the afternoon and was hyper. This is a definite improvement.
