CAM (indiginantly): I am not MAKING a ROCK pile. I am MAKING a piece of ART!
CAM has a rock collection. She doesn't call it her rock collection, though, just her COLLECTION. We have a little tile-mosaic-topped table in a nook in our living room -- we got the table ages ago in the garden section of Target and used it in an old apartment years ago to drop keys and such on when we came in -- and it's become her COLLECTION table. It's precious to her, and consequently, precious to us. And we have rocks from everywhere we go ... If I am not aware that she took any, I often discover them when I take the laundry out of the washer and there's a little collection of rocks and pebbles on the bottom of the basin.
