When something happens, we feel the need to explain, both to ourselves and to others. The truth is that, there are times when we truly do not know what led to the outcome, or we cannot pinpoint a single cause. And that is ok.
The world is complex, and has many moving parts at all times. When we try to find a single cause, we might be doing so at the expense of truth. And that may not help us if we are the in the same position tomorrow.
So maybe, instead of trying to find the magic bullet, we can try to understand or appreciate the full context. And that is ok, too.
