Graveyard Rubbings

Did anyone else ever do these as a child? It's called Graveyard etching or rubbing. My mom used to take us up into the graveyard near our house with some crayons and white drawing paper and we would place the paper against the tombstone and rub the craying over it so that the persons name and the date of birth and death showed up on the paper. I guess you could consider that morbid, although as a kid I never did. The stones were very old back then and are in even worse shape now so I doubt you could even try to rub against them these days. That didn't quite sound right LOL
