I'm so sorry, TRL. I was half-thinking you might check in on the chat last night, and when you didn't I wondered if it was because Oliver had died (although I knew it could have been because you're in Poland right now). I'm so glad your parents were with him; I know you must feel awful that you couldn't be there, but it would have been much worse for you, I suspect, if he had died alone. I'm also glad he didn't have to suffer long, since it seemed pretty clear that he wasn't going to get better.
It's good you're doing something absorbing right now. My sister, who recently lost one of her dogs, has far too much time to grieve, and it's dragging her down a lot.
Once more, with feeling, SO, SO SORRY!
