Just like so many other AFOL's, I returned to LEGO some years ago when buying presents for my kids. So I made up for all the time missed: too much Technics...
My interest is Technics and Mindstorms, and for my daughters there is Friends, but the six year old helps out with the Technics too, and for our son there we have plenty of Duplo to explore.
My wife thinks we already have enough LEGO, she may be right, I was able to build Jurgen's Ultimate 42009, and missing parts... On the other hand, can one ever have enough LEGO
