Prep and ground rules for kids starting freshman year?

Looking back I had to chuckle when reading this thread. Way, way back in the day as a teen, I wouldn’t say my father had rules, as much as he had two hopes.

  1. don’t be brought home by the police.
  2. he wanted a DIL before he had a grandchild.

Bad news: I failed twice with hope #1. Just stupid dumb teenage stuff.
Good news: although there were a few days of restless nights, fortunately a monthly event occurred in a young lady’s life, meaning I succeeded with hope 2. Learned an invaluable lesson about protection. (It only takes one time)

I had mixed success with imparting my dad’s hopes to my S. He had no police interactions (yeah), and W and I have a wonderful DIL although the first of two grandkids arrived 4 months after the wedding…
