Mailman was the first to congratulate

The mail carrier's treatment of packages and papers reflects in no way their level of education

It says it right on the diploma, "do not bend". So either the mailman is an illiterate idiot or a careless lazy ass. Don't know which one is better.

Or maybe not everyone has time to read a million letters just to check if they say "do not bend". Your inconsiderate attitude irks me

Yes, maybe not everyone has the time to do their job.
Funsubstance, where defending people who are inconsiderate to their customers from whom they get their income is ok, but don't you dare call them out on it, that's inconsiderate!
