Lego fans are devoted. This article by Damian Whitworth demonstrates just how devoted. But let me just hit on this one bit:
And therein lies the crucial truth about Lego. Parents don’t just buy it for their kids, they buy it for themselves. Or rather, dads buy it with themselves in mind.
The first sentence is definitely true. The second one, not so much. Well, at least for us. The flood-gates on Lego were unleashed when both parents argued over who was going to build the set with the child. This was solved by getting two sets and some extra children.
Whitworth then goes on to imagine building houses -- yes, real ones -- with Lego. One thing is for sure, it will make rearranging things relatively easy.
