I’ve seen one person choke in my life.  I had no idea what was going on, but knew my neighbor was struggling to find words, which were on the tip of his tongue, but blocked.  Fortunately, another saw and came to the rescue.  Every day, we watch others struggling for words, but not able to find them.  As the Church, we are called to speak for them, dreaming of the day such speech will no longer be necessary.
