"I'm never sad when a friend goes far away, because whichever city or country that friend goes to, they turn the place friendly. They turn a suspicious-looking name on the map into a place where a welcome can be found. Maybe the friend will talk about you sometimes, to other friends that live around him, and then that's almost as good as being there yourself. You're in several places at once! In fact, my daughter, I would even go so far as to say that the further away your friends, and the more spread out they are the better your chances of going safely through the world."
