Whatever one of us asked the other to do - it was assumed the asker would weigh all the consequences - the other would do. Thus one might wake the other in the night and ask for a cup of water; and the other would peacefully (and sleepily) fetch it. We, in fact, defined courtesy as 'a cup of water in the night'. And we considered it a very great courtesy to ask for the cup as well as to fetch it.

Both Heaven and Hell are retroactive, all of one's life will eventually be known to have been one or the other.
