Lucy was talking about improving her Spanish. She said, one of the best ways to get fluent in another language is to shack up with someone. And I said learning by doing as it's called. So that's learning by doing, but also doing can mean having sex,. Right? It depends heavily on the context. Don't be scared of the word do. It's not always going to be potentially an innuendo. For example, if you said, oh, I'm just doing my homework, I don't think anyone would misunderstand that. But nevertheless, there was a bit of self deprecating humor in there as well.
