Dear Jack,
You and I have a largely unspoken understanding: I don’t worry about you getting yourself into trouble, because you know how to have fun without getting into trouble.
I never worry about where you are or what you are doing, because I know you’ll text me right back if I need you.
One day this past week after school, you told me you were heading out with your friends; taking your dirtbike to go hang out. As it reached close to 7 pm, I texted you that I needed you home from dinner.
You and your buddies had been out riding, and then hanging out around a campfire.
I love it that you and I have this kind of understanding and relationship.
Love,
Daddy
