Once upon a time...
Growing on an old stump, where there once was a rather large tree, stood a teenie, tiny, little tree. He was so perfectly shaped and stood straight and proud in the sunlight.
To the many infinitesimal, crawling beasties, he was not a tiny tree at all, but, in fact, a full sized tree that stood strong and alone where no other tree could grow. This made the tiny tree very important.
Only the birds and the butterflies knew that the tree was so small that he could hardly be seen. Even so, they kept far away from the tiny tree, respectful of his place in the world.
One day, a butterfly noticed the grass began to creep over the old stump. It quickly whispered to it that if the tiny tree should ask to please pardon itself and say, "Excuse me, but I am the largest vine in the world and must stretch out for I am running out of room, I hope you do not mind me." The tiny tree didn't mind the largest vine in the world passing through at all.
