Living in my basement at 45?

I fear my child is codependent. He either can't, or refuses to, play by himself. I don't think it's anything I've done, I've always been all about independence and encouraging him to do stuff on his own. He's just not interested. He spends his day yanking on the hands of whoever will get close enough to grab. He hauls us all over the house. He's like my little shadow, everywhere I go, he goes. He'll entertain himself for a few minutes, but it never seems to last long, and then he's demanding a playmate. I really don't mind, it's just that sometimes I need to get something done, like clean, or blog (he's currently trying to yank on my hand as I type), or pee, and he's kind of an impediment to that. Right now I think we'll just take it as a compliment that he considers us the most interesting things on the planet, and remind ourselves that someday he'll be a teenager who doesn't want us around. I'm just hoping he grows out of it before college.
