I try to be careful with language around Lucy, because she is at the mynah bird stage. However. One can only be so careful. Many words that you wouldn't think are perilous...are. Some examples:
And there's no going back, either. When I taught her "Dildo," I said, "Oh, I meant--it's an aardvark! Can you say aardvark?"
Lucy, proudly: "Dildo!"
I have no idea if an aardvark and an armadillo are even in the same genus, but hey, zoological accuracy was not a top priorty. Luckily, it's unlikely to come up in polite conversation. Or impolite for that matter.
However, with my luck, someone will mention that funky shirt that the armadillo has on, and it'll all be over.
