Wild Thing has been busy drawing animals. He was showing me some of them, and telling me facts about each one. He pointed out that a certain animal was "ternal". I asked him what he meant by "ternal". Wild Thing looks at me like I am totally stupid. He says, "You know, mama. Ternal means that it's awake in the day. Not ternal is awake at night."
I guess I know what tomorrow's vocabulary lesson will be.
