Well, I personally am so inured to hostility that it takes a chunk of concrete to the skull a couple of times for me to notice it, but, as a healthcare person, I can say that:
Withdrawal from 40 years worth of nicotine, tar, carbon monoxide, acetone, ammonia, formaldehyde, hydrogen cyanide, methane, naphthalene, nickel, cadmium, and {gasp} vinyl chloride which, at a pack per day equals about 150,000 doses of these chemicals in one year, up to 90 percent of which remains trapped in the lungs, can put a person on edge.
And I would say that, if I didn't already know Maggie to be a testy one from the get go
Anyway, FWIW, I think Stepan's suggestion is the most efficient, especially considering the recent comment-spam burst as well - even on my remote little site
