Teaching my boys how to shake a man's hand properly
My grandfather taught me when I was young and I'm making sure my sons know how to do it right. Firm grip, look them in the eye, and mean it. Had them practice with me and then we did it with my neighbor. Mr. Johnson told me they were the most respectful young men he's met. That's the kind of reputation I want my boys to have. It starts with little things like this.
Genuinely one of the best parenting moves. I learned this from my dad too and it's stuck with me. Your kids will remember this and honestly it'll give them a leg up in job interviews and first impressions.
