My sons love their Legos. I think we have 1.5 billion strewn throughout our house at any give time. If I had a dollar for every time I’ve sucked one up in the vacuum, I’d be a wealthy woman.
Heh...we had so many Legos (and whatever the cheaper ones were...Duplos?) when I was little, that every so often Mom would get sick of stepping on them / sweeping them up and offer us a penny for every one we could collect. I generally made a couple of bucks each time.
I think they're long gone now. But we spent many happy hours with those...and Tinker Toys...and old wooden blocks.
The best toys are the ones that require a good amount of imagination and creativity!
