I like to bug Nigel as much as I can. Don't feel sorry for him, because he has the same pleasure. One great way to bug him and get a good laugh myself is to tell him in a very authoritative tone some medical wives tale, some extremely simple medical fact, or as in this morning completely ignore his medical credentials.
As I am getting over a winter flu I call out to Nigel and in a serious voice I tell him I need him to Google me something when he is next on-line. "Nigel, Google 'white bits in mucus. explain.'"
He looks back at me and in an equally straight face says, "hon, I deal with science and progress not whims."
