I think it’s just human nature to be caught up with irrelevant things and lose sight of the big picture. It’s also human nature to come to the aide of those in need and to come together in times of trouble.
People often ask why Jews, especially Israelis fight among each other. We are all family, sometimes, families fight but when needed, we all come together.
No need to be harsh on yourself or others, it’s just how people tick. We all need to just try to keep things in perspective and not get worked up over nonsense.
