Thank you for the kind thoughts and comments. His appendix hasn't in fact perforated (yet) so they have given him morphine to make him comfy while they do tests to rule out other things. He's zonked out asleep now. I popped home to have a bath and get some food. Surgeons were open and courteous in explaining everything to us. They may operate tonight or wait until tomorrow. I am still hopeful that he might be out for Christmas.
