The day I realized I'd become my dad

So I was grilling last Saturday and my son came running over. Instead of thinking 'ugh kids are annoying' like old me would have, I got this weird proud feeling and spent the next two hours teaching him about fire safety and meat temps. Then I caught myself explaining the structural integrity of our deck railing to a 6 year old. Exact same thing my dad did with me. It hit me hard. I'm officially my father now and honestly it doesn't suck.
