I suppose it could be a good sign, that he's getting a little bit bored... might be a sign that he's well enough to want to get moving. He's watching his siblings having a busy and fun holiday, and he feels grotty and can't even stand up straight, almost two weeks after the Vas cath was put in and taken out (page here describes the various types of IV lines - don't scroll to the bottom if you're at all squeamish). I'm thinking to put some pain relief into the equation tomorrow so that he can mobilise a bit more.
At least he managed to run off a bit of caligraphy today... It's a bit like coming to the end of the summer holidays with nothing to look forward to. Earlier we were looking at the Kinkaid jigsaw that was completed when he finished treatment last year... Perhaps I need to set him some SMART objectives (Specific, Measureable, Achievable, Relevant, Time based).
