A few I remember...
As a kid, you never interjected yourself into adult’s conversations unless you were asked into them.
If you had something and your sibling didn’t, you had to share…or get it taken from you.
No curfew, per se, ….. I could stay out till 4 a.m. on a Saturday night if I wanted, but I was getting up for church on Sunday morning; and there wasn’t going to be a discussion about it, either.
As a parent, I don’t have a lot of "rules." I just have to trust that the examples I've tried to show and discussions I’ve had with my kids will take hold. My eldest just finished her freshman year, living on campus. I was nervous, texted her 3x a day the first week+ of the semester, but I know what her mom and I put in her. She did fine (honor roll student, (3.8 gpa,) made lots of friends, active on campus) and is doing great.
I, on the other hand, had to learn to calm down.
When your time comes, you’ll be fine.
