I don't feel like it is a win-or-lose sort of thing. I surrender my soul to God. I surrender in a game when playing with a child, giving them enough play to make them work for it, and then again, sometimes I don't... we can't always win. Best to be taught how to lose gracefully also. I don't see it as a failure. I do not surrender because I am lazy or don't want to put the work into it, but, I guess I just don't think about it.
Saying that, if it were surrendering my child, or something important, never! Good morning from here!
