Now we joke that LJ is the new letter, thus... "I'm gonna post about this!"
So, here we are.
Dear Air Conditioner Fixing Person,
While you did see an ash tray in my apartment as you fixed my air conditioner, don't you think it was a tad rude to smoke in my apartment anyway? At the very least, you could have USED the ash tray, or flushed the toilet so I didn't have to see your cigarette butt floating in it.
