Yeah, you are right. I certainly wasn't trying to be creepy and you can rest easy that I haven't pushed my kids like I was pushed (in fact the kid in question regrets that I didn't push him).
I just am dismayed that my kids don't build stuff. Building stuff has brought me so much pleasure and satisfaction. I want that for them, for their happiness, not mine. I'll be gone one day and I want them to be good whatever they do.
