Don't feel stupid Goofy - I think we've all had occasions when we've missed the obvious. My worst moment was when I asked for help for the next in sequence. it was something like C V B N??. I typed the letters very carefully so I didn't make a mistake and didn't realise I was typing letters on the bottom row of the keyboard. I really did feel stupid when someone gave me the answer.
Best wishes for your hospital stay - hope all goes well and you're home again very soon.
