Being pregnant reminded me of one of my favorite stories from work:

Student: "see that lady, she's a lesbian" points at a Somali woman who is on the playground
Me: "do you know what a lesbian is?"
Student: "yeah, that means she's going to have a baby"
Me: "actually a lesbian is a woman who dates another woman, when you are going to have a baby you are pregnant, is that the word you meant?"
Student: "oooooh that's what a lesbian is" and he runs off to play on the jungle gym.
