They were:

Everywhere during my early childhood.

Mudcake decorating material.

Currency, as in four stickerballs for your mom’s (old?) bracelet while we played Jewelry Store. I remember feeling that something was not quite right with these transactions. I think I remember giving back all of the jewelry, but that may be revisionist history.

Objects to throw at friends during friendly and unfriendly times.

Craft material or art in themselves, depending on the mood of the beholder.

Things to rake up.

They are:

Hardly anywhere.

Old friends that greet me as I step into the park for my walk at lunch. How did they find me 50 years later, 600 miles away?

Things I hope the groundskeepers forget to rake up.
