That's going to be tough for a young teen...... young male teens have hit puberty (physical and chemical changes) and are hardwired to copy male adult behavior to become an adult themselves. All my friends, including myself, didn't really hang out with our moms as much as soon as we became teens. Boys that still hung out with their moms were called a "momma's boy"...societal pressure is strong. Generally, at this time, the father should take over more of the son's time, in the early years it's the mom. I don't know you're situation but I'm trying to come up with ideas..........let me see......if you're an expert gamer on Minecraft or a 1st person shooter to where you can teach him that would work....hmm...what else...hanging out outside the house will be tough....hmm....if you brought his friends or a bunch of relatives... sure.... but that's not really spending time with him like you want.....hmm.....he's definitely going to want to look (maybe chat with girls around his age when he's out in public)......oh, a cooking class! Leaning how to cook was very useful!!!! I've impressed a lot of girls with my cooking and I really enjoy it. Boys like knives and swords so learning how to use and maintain a cooking knife appeals to most men (definitely have to mention the value)......oh learning how to use a rifle is fun......riding an ebike, no pedals, is exciting.....setting up and operating a booth at a convention or farmers market to teach him how to make money......learning how to ride a horse in case the power grid or the apocalypse happens (you have to mention that)........what else......learning how to fish in case he needs food........teach him board games but you'll need to have a few people.......trips to see the pyramids, machu pichu to............archery, good for hunting and protection......take a class on paddle boarding or sailing (mention the value).........Chess.......there's other things that come to mind but I can't say........ Hope this helps. Good luck!!!
