My parents started my older brothers on Duplo's when they were young, and then got them Lego's when they got older. My younger brother and I got some too along the way, and when the older siblings grew out Lego's, we inherited the collection. My older brothers started organizing the Lego's into plastic fish bait containers, by kind of piece. We have followed in their foot steps, and have continued their legacy of sorting Lego's and building.
