I feel that what our brain’s answer to what we should do in any situation is never constant. Especially in social situations. It changes maybe because we adapt to a new outlook on a situation by just waiting a few seconds to let it sit in. The longer it sits the more answers you can come up with. Perspective is everything. It changes the view of the situation and the reaction you think you’ll get. I don’t think should does exist. There is never one correct answer to anything.
Stay centered and you never have to worry about this or that. You just go with the flow and react how you should. However that may be. So when we seek for our own true center, then all else falls into place.
