You can often pinpoint your favorite moment in a particular stage performance, when an actor does something so fresh or unexpected or wonderfully human that the worlds of fictional "reality" and actual reality blur in the most extraordinary way. Ray Gabica, in My Verona Productions' current presentation of Tuesdays with Morrie, doesn't provide one of these moments. If you try really hard, though, you might be able to narrow your favorites down to about 50.
