I guess your brother fancies himself the possessor of razor sharp mental acuity. He must be a ball to be around. Bet he's a real wit.

Actually, a decade can be any sequence of ten consecutive years, which is beside the point.

Congratulations on upgrading your life. Good for you! Inspiring. Things can change.

As or my experience - My brother liked to drop little insults that he'ld insert into a fairly normal conversation. I just ignored them and thought how pathetic on his part. He dropped out of my life. I never felt bad for myself when he'ld do that . . . just sad for him.
