"I am a part of all that I have met." - Alfred, Lord Tennyson - 1809-1892
We are lucky to know other people. Some of them are our "better angels," some of them are our "demonic angels." Most of the us encounter a healthy allotment of each.
There are no "self-made" Human Beings. That is a ridiculous, and frankly pernicious idea. We are all in it together whether we want to acknowledge it, or not. Really, that is just the way a life rolls out. Connected.
