Vectors

"Mr. Kelley, I need to leave your class at 11--here's my slip."
"OK, thanks; are you OK?"
"Not really; mom thinks it's some contagious virus but it may be Strep."
O good; thanks for telling me...from 2 feet away... right toward my face.

As a teacher this exercise is weekly, sometimes daily, so is it any wonder we may be 'a little congested' [teacher-denial-speak for "I'm sick but don't want to admit it"].
So goes the cycle of denial-borne, air-borne contagion.

I got my flu-shot last week.

Too bad there's no cure for the common cold (cough, hack, cough, sniff...ache).
