The Fossil Lady
We live on an ancient sea bed here north of Austin. The fossils are laying all over the ground and my wife is a collector. When we were in Florida it was sea shells. Here it is fossils. For instance:

She found these within a quarter mile of our house. The construction workers who level the ground in preparation to building the latest development are used to seeing her, walking bent over in the sun scratching at the freshly turned rocky terrain.
I'd likely be a little more interested if I did not find them all over our house. Everywhere. She has some boundary and some hoarding issues that I have a full time job keeping in check. At least it is not shoes.
For Halloween she created sandwich bag of candy. Into each bag she would put a small fossil or two along with a carefully hand lettered note about what it was and how old it was. She spent a lot of hours on this and had a huge bowl of them. It was a labor of love. She made me promise that if I found any of them on the street I would just pick them up and never tell her.
Turns out she was the hit of the neighborhood. The kids loved them, a special surprise for them. She ran out long before the kids stopped coming around.
At one point a kid came up to her and asked: "Are you the fossil lady?"
