Whether we want to acknowledge it or not, there are no rash decisions. Nothing occurs, at least initially, without some semblance of internal deliberation. The difference lies in the conditioning.
When we view someone as inconsiderate, what we are really saying is that they didn’t take the adequate amount of time we’d have liked in order to decide on and execute the (offensive) action. Had they exercised a bit more patience, they could have analyzed the effects it would have from both perspectives and chosen the innocuous option. Yet conditioning is individual. Someone who has characteristically made decisions with only themselves in mind will continue to do so, until they esteem another’s opinions/emotions enough to shift their general paradigm. This is their only frame of reference and we can’t expect that to change after a declaration of intent. We can only wait for dedicated effort.
If we can’t wait, then we should remove ourselves from the situation. We have to deal with things (resolve, not resign). Second thoughts are to seek confirmation, not to feed doubt. So think twice about what you accept for and apply to your life.
