Like Father Like Son

 1. Once more to the lake is not in chronological order. He starts off being a boy and going to the lake with his dad. Then he brings his boy to the lake later in life when he misses the peace of the lake. Then as the story goes along, he keeps visioning himself as his own father, and then as himself again. He always says that the lake is always there where he left it, only the people are the ones to get older and change.

2. At the end of the story it talks about death. This means that as they leave the lake, a new chapter begins. He now has shown his son the lake and it is his turn in the future to show his son the lake, and so on. It seems to me that a part of E.B has died because he has to move on from the lake.
