I’ve only had butterflies land on me a handful of times, but I can do it as many times as I want here!
In elementary school, we’d play with caterpillars. One time, I took one home and tried to raise it. After it turned into a moth, I brought the box to my neighbor’s house, because their son was also raising a moth. As soon as I got close, my butterfly started going haywire in the box, and apparently so did his. We put them together in the box to see what the heck was going on, and they immediately started mating. That was an interesting experience.
