Sometimes leaving home teaches you which parts of home live inside you.

You leave assuming home was the place, and discover that some of it was portable. The way you cook, the tone you use with strangers, what you consider polite, what you find funny. Those travel with you and show up plainly in a new setting, where they suddenly look like choices rather than facts.

Going away for a while is one of the few reliable ways to see this. Notice what you keep doing that no one around you does. That is the part of home you carry, and it is usually worth keeping on purpose.
