My right arm has spent the last week or so trying to fall off again and since my neck is also screaming at the moment I'm currently resting the right arm in a sling to give my neck/shoulder muscles a break when the arm isn't in use.
Today in the smoking room at work...
Him: Oh no, your wrist playing up again?
Me: Nope, this time my arm's trying to fall off.
Him: Your shoulder's slipping out?
Me: Yep, that's right.
(thinking wow... someone's getting it!)
Him: Ow! If you were a horse they'd shoot you.
Hmm. Charming. He meant well, bless him, but how the hell are you supposed to react to that?!
