What a fun and educational thing to do. I keep loads of craft and painting supplies handy, since that's what I'm known for, but to add things at random seems fun and a great way to start conversations... HOWEVER, I might need some awfully sophisticated and challenging items since my all but two of my seven are already college age: one entering this year, two already graduates and a fourth in his second year. The odd man out chose not to go, which I applaud him for.
