We used to see them on the beach sometimes when I was a kid in Massachusetts, and sometimes floating in the water around us. Ew.
Sometimes we would accidentally step on a dead one on the sand. Double eww.
Once when I was swimming I put my hand right through one. There’s no word for that sensation.
I had to really overcome a lot of prejudice around here, open my mind with a crowbar, grit my teeth and celebrate some real diversity to get to the point where I could call myself a “jelly.” I still try not to think about it too much.
