Celeste ran up on to the porch, which isn't really a surprise. Her first instinct is to move away quickly from most animals and other things that aren't dogs. Quinlan, however, overcame her sister-induced fear and came over to take a look.
She got a bit giggly about the dirt that was all over the worm, and how it was twisting and then moving along my hand. Celeste eventually came over to look, but Quinn was the only one who would touch it. It took a little while, but she finally let me put the worm in her hand.
We put the worm back in the soil and a few minutes later, Quinn was back looking for it and wanting to hold it again. (She also was convinced the first worm had been a boy and this time she wanted to see a girl worm; I passed on trying to explain hermaphrodism to her.) After the third time holding a worm, I suggested to her that the worms probably wanted to get back to digging in the yard ... and it was time to go in for a snack.
*I'm not putting a scientific name for earthworm here because I have no idea what family of Lumbricina the individual worms in question were, much less their species. In googling around to see which species were common to suburban Maryland, however, I found out that the vast majority of earthworms in North America are non-native invasives. I had no idea. One fairly recent study of worms in the Baltimore–Washington suburbs found that most of them were non-native; another study found that only three of the 12 species present were native.
