I will admit, some of my more favourite moments are when one of my boys will build with me. Or go shoot some archery. Or just play a game.
The funny thing is, being a parent, you (at least I) feel that absolutely everything I do is 100% wrong. I look at my boys now and wonder if I've passed anything down to them at all. That said, I know where you're coming from. I'd be lonely without'em, so I feel for you.
And now that's a pretty good looking build you've got going there. That is a lot of small parts that I am pretty sure my cat would love to scatter for you, given the opportunity.
