Lovely story... reminds me:
At my grandmas house there are 8 concrete sidewalk squares, one for each of us grandkids with our handprint and name on them from 1983. When she died I wanted to go steal the squares for keepsake. I didn't, pretty sure it's part of city property. But my little 3 yr old handprint is still there, mostly covered with overgrown grass and so faded that you can't read the name above it. But I know it's still there. ❤️
