I had seen what seemed to be a father & son, in my neighborhood, changing a tire together. I can't remember the last time I saw this - except for when I taught my sons how to change a tire. And it inspired me. My goal is to teach my son this week something/anything that will be useful...even if rarely needed.
I think it'd be badass for all of us to make the attempt to do some version of this. It may incite eyerolls or a "Why do I need to know this?" But it's the memory that will matter. If you have a favorite recipe, hobby, skill that your son may not know you have, etc. - do it with him and report back what happens. And I'll do the same! (Picture is a bonus)
