Always give a word or sign of salute when meeting or passing a friend, or even a stranger, if in a lonely place.

A story is the shortest distance between being a stranger and being a friend.

My secret friend,
Oh, take me to the river.
My secret friend,
So we can swim forever.

There were people everywhere on the city street, but the stranger could not have been more alone if it were empty.

A friend of mine gave me a rainbow and it made me happy. So, I in turn, gave it to a complete stranger and then it made both of us smile.

A stranger is just a friend I haven't met yet.
