I had Lego back when I was a little kid in the late 60's and early 70's, with a huge box of bricks. They were all white or red, back then. I never had enough windows or doors for what I wanted to build! I used them so much that a lot of them wouldn't stay together anymore, they would fall off if turned upside down... Lots of great fun.
Flash forward to 2014, and I have returned, and am obsessed with the modular buildings and creating a town, its taken over half the dining table so far. I can't wait till the next set comes out!
