Speaking of family sayings freaking other people out:
D was about 12 when she came hiking with me and a few of my friends. At one point a friend did something and asked if D was OK with it. The response: “It’s OK. I’m just scarred for life.”
There was no immediate response from my friends, but later they asked if D was OK. They had been talking between themselves all day, worried. I just laughed. It was our way of saying it was all good, no problem. My Ds had been saying it for years when something unconventional happened. I believe they got it from some movie once upon a time.
