If you speak two languages, you might feel like a slightly different person in each. Both are you.

Each language carries its own rhythm, its own jokes and its own people, so you really are slightly different inside it, warmer in one and more precise in the other. That is not a split or a pretence. It is one person running on two sets of equipment, each with its own range.

Notice which of you shows up where, and whether one of them has gone quiet from lack of use. Spend an hour this week in the language you are using less: a call, a film, a conversation with a relative. Both versions stay available only if both keep getting exercise.
