"most people just see "rocks"

Which reminds me of one of the most interesting stories I have heard of such things.

I knew a family who had several kids...one, a little girl of about 7. AQt one time, they had to move, and as things were being packed, they discovered under the girl's bed a box...of rocks & concrete and asphalt.

"Heather, what's this?"

"Oh, that's my collection of street!"

"What do you mean...why street?"

"Well, this one is part of the curb from our house, and this one is from in front of Grandpa's house, and this one is from where they repaved at my school...and this is from Sally's driveway. and ...."...etc...etc.

She had told no one... but she had her 'touchstones'.
