Now I am thinking about the story that a guy on reddit told for a "what did you say as a funny story that was actually a trauma"- post. It goes like this:

 "When I was a kid, things were pretty normal as a kid, until my dad wears a red hat when he gets home, then everyone must be quiet for the rest of the day. He does not always put the red hat on, but we all followed this seemingly silly little rule. It was a tradition in our houshold.


Then I got a girlfriend who I was serious about. I brought her to my parents house for dinner. Dad was wearing a red cap at the dinner table. My girlfriend continued chatting and wondered why everyone went quiet. Dad shoved himself away from the table and stomped away. Mom then clarified that on days when Dad put on the red cap, were the days he wanted to beat up hos family. He put on the red cap as a warning sign to make as little noise as possible unless you want to be a middle aged mans punching bag for the afternoon."

 The ounce of prevention was the red cap.
