When on the Internet, a smart person pays attention to when things were posted. For one thing, it keeps you from 'helping' someone who made the request years ago and will probably never appreciate your efforts.

If you see an asinine post and know where the poster lives, it is a good idea to figure out what time of day it was posted. The wisecrack about a frigid soprano was probably posted in England about midnight. I'd bet you dollars to donuts the poster had had a few beers and had come home, postpub, cranky, tired, and ready to inflict his bad mood on a defenceless world.

Particularly if the victim (a female teacher) is likely to be smaller than him.
