When we leave to another place we sometimes leave fingerprints after us: we leave our books, postcards from friends, teapots, from which we were drinking so many cups of tea every evening.
There is a good, very clear feeling about time when we leave: we make some space for something new to come.
One of the reason why I like to leave is because you can also give all your things to your friends, so that your fingerprints become their fingerprints at some point in time.
