The boy is a thinker

Spencer asked me, "Mom, will Santa leave me a lump of coal this year? Have I been good or bad?"
I replied with, "Sweetie, I think you have been pretty good. I wouldn't worry about getting coal."
....Spencer thinks about it for a couple of minutes....then says:
"Well just to be sure can you call Santa and tell him that he can't bring me coal because I am pretty sure it would flare up my asthma."
