Sometimes when a person needs company but not conversation, if they can tolerate a pipe, it is a good way to spend time together in quiet, like after someone has been upset by a life situation or is in grieving. I can see a pipe/compassion connection there. Actually, the room note, if pleasant to the other person, might accentuate the presence and enhance the quality of quiet. Maybe? It might reassure the other person that you are content and present.
