Random memory: In grade 4, one of my classmates was walking around with an inflated condom for some reason. Now I wasn't entirely sure what a condom was or what it was for. I could identify the word "condom" with a wrapped condom, I could vaguely associate "condom" with "gay" (I didn't fully understand what "gay" meant either), but I didn't know what a condom was actually for, nor had I ever seen one up close.

So anyway, this guy had an inflated condom. Someone announced "Mike has a condom!" I looked over at Mike, looked what he was holding, and thought "That isn't a condom! That looks like a balloon or a medical device of some sort. A condom is a little plastic square!"
