I like going out of the house, but I love returning home. And I like traveling sometimes, but after a trip, I especially love returning home. It means I love that moment of coming back to my favorite place to be.
Things and animals can return, too. A boomerang returns to you after you throw it. After birds fly south for the winter, they return to their homes in springtime. And if you're tired or in a bad mood, just get some rest and some food, and maybe your energy will return, along with your happiness.
If you just bought a toy and it immediately broke, you may be able to return it: bring it back to the store, and get your money back. Usually, we can return things we bought if they don't work properly. But no matter how much you might want to, you can't return your baby siblings to where they came from. They're here to stay.
