Post-courtesy years

The period of life, observed in the elderly, where the rules of polite conversation and overt public embarrassment are no longer followed. People in their post-courtesy years see no need to be polite and blurt out exactly what they think, regardless of how embarrassing or unkind it is to the subject or surrounding parties. Often manifests in the late 70's.

Grandma in her post-courtesy years, said "My son-in-law has a big nose just like yours."
That senior citizen just said women don't need any education and should just have babies.
Grandfather said, "I can say anything I want because I have earned the right."
"Oh, I see that you have gained weight. But you have always been kind of fat so it doesn't show."
