I used to get it for Christmas every year as a gift, but I was never disappointed. Every year, I would get several of the little kits. I’d make one on Christmas and then another the next day, and slowly build all of them.
I am, of course, talking about Lego.
I remember building with them, always following the instructions closely the first time through. And then after about two weeks, I’d take it all apart and reassemble everything and change it, using the same parts to build something completely brand new.
