My Dad was good for pithy sayings.
"Don't let your mouth write a check that your butt can't pay for"
"When someone/something knocks you down, get back up and hit them/it harder"
"Close mouth. Open ears. Engage brain"
"If your friend stuck their head in the toilet, would you follow them?"
I always hated the last one!
I'd give anything to hear him say it again.
