On Thurs afternoon, I went to a park, came back home briefly, used the bathroom, drank a glass of cold dihydrogen monoxide, and went out to a different park for a little while before coming back to grab what I'd be bringing to kiddush after tashlich at the beginning of the 2nd night of Rosh Hashana.

While I was in front of the toilet, I felt a tickling sensation on the back of my neck, so I instinctively grabbed it with my only working hand.
