Are you someone who is often silent?
When you are silent, what does it mean?
Rabbi Eliezer Diamond - Aaron's Silence http://www.jtsa.edu/aarons-silence
"There is, I believe, another possibility as well. Perhaps Aaron's silence was a form of disengagement, in at least two senses. The first may have been an emotional reaction beyond his control. The horror of what had occurred was so great that Aaron's mind may have shut down, thereby blanking out what had befallen his sons. Perhaps it was only in this way that he could bear the pain of his loss at that moment.
It may also be, however, that Aaron's silence was a means of disengaging from his persona as priest. How difficult it must have been for Aaron to serve God in the very place where that same God had taken the lives of two of his children. Aaron continued his holy work, but there was some part of him that was now silent, that did not turn to God in prayer and praise as it did in the past. The fire that killed Aaron's sons had wounded him profoundly as well."
