Became a homebody and I'm totally fine with it
Used to be out every weekend with buddies, road trips, bars, you name it. Now I'm that guy who wants to stay home on Saturdays and build a fort in the living room. My friends give me grief but they're starting to get it now that some of them have kids. I don't miss the hangovers. I miss the spontaneity sometimes and just not having to plan everything around nap schedules. But building memories with my family beats a night out every single time now. Weird how your priorities just flip like a switch.
Your buddies probably think you've changed but you haven't. You've just figured out what actually matters. Weekend at home with the family is way better than any bar crawl.
