Little Plastic Bits

This time of year I venture into the depths of my children's assorted toy boxes, drawers, closets, caves and caverns for a good spring clean. I try to match all the games and puzzle pieces to the right boxes. Anything that can't be match gets thrown in the bin. Anything that the children have outgrown (or that I find just too annoying) gets either thrown in the bin (if I don't want to risk annoying countless other parents) or put in a big black bin bag headed for the charity shops.

I have discovered an uncanny talent which my son possesses. He showed a penchant for this talent at quite an early age. I'm wondering if there is any way to make any money with this talent. Oh perhaps not!

This son of mine cannot remember to put his dirty underpants in the laundry basket. He cannot remember what I ask him to do once he leaves the room I am not in. He has the memory of a newt.

Unless you are asking him which toy this little piece (smaller than a fingernail) of orange coloured plastic goes with. Or this turquoise square? Or this yellow tube?

He knows exactly which toy every stray piece of plastic goes with. He will tell me "It's the base that goes with that grey Transformer that was missing the arm that you threw away last spring clean." How does he remember that. I picked up this little clear yellow plastic bit and he identified as as belonging to a toy we threw out over 3 years ago.

My daughter is also displaying similar tendencies when we started on her closet. Are we all born with this? Do we then grown out of it? Are my children the only children that do this? Can we make money from this?
