We had some old friends over for dinner last night, for the first time in about fifteen years. When they arrived (fifteen minutes late!), they announced that the husband had a stinking cold! He spent the whole evening blowing his nose (LOUDLY) and sniffing. I've recently been in hospital, so the last thing I need is another cold.
AIBU to think that you should let someone know if you're ill so that you can work out whether to rearrange?
