I don't think this was dumb exactly, just naïve. I didn't know fireflies were real until my 20s. I thought they were just a made up thing in storybooks.

I was rooming with a girl I barely knew for the summer and was looking out the window while washing dishes. You know how fireflies tend to sync up? Suddenly I see hundreds of tiny yellow lights turn on and then off. On and then off.

I yelled for her to come in (at least to my credit I was more fascinated than afraid!), and she ended up dumbfounded that I had never seen fireflies before!
