Sitting in Michael's Lap
My reaction to music is odd in this regard.
If I am watching a film, sometimes the right music is just enough to push me over into quiet weeping (but only if the room is dark - I have this neurosis about crying where anyone can see me).
If I am simply listening to music, I don't cry. Never have yet, at least, without some other stimulus ... like I am already depressed and would have cried eventually anyway.
However, when I sing, I often get choked up when the story gets sad. I seldom can finish Lorena McKennitt's adaptation of "The Lady of Shallott" by Tennyson without my voice becoming querulous at the end.
