Legos were my favorite childhood toy. Put them away around late elementary school and forgot all about them. Now I'm almost 30
and have a wife, son, and another son on the way. A few months ago, my three year old son found my old lego box in my mother's basement it's "been on" ever since! Been picking up newer parts here and there and have been having a blast creating minifigs. My MOC ability is still fairly week, but I've been spending a lot of time here, flickr, mocpages, etc, and have been continuing to grow and learn.
It has been so much fun getting to share this hobby with my son. Hopefully he continues to enjoy it as much as I do.
"What's wrong honey? I'm buying these legos for our son!"
