Pittsburgh Public Theater presents, "Good People," by David Lindsay-Abaire and directed by Tracey Brigden. This distance between Boston's Chestnut HIll and Lower End is measured in more than miles. Mike and Margaret both grew up poor, but he made it out and became a doctor while she is stuck-a single mother who gets by on sarcasm and bingo games with her pals. When they meet again, an invitation leads Margaret to his luxurious home and into a turbulent conversation with Mike and his surprising wife. This tough and tender play looks at luck, choices, blame, pride, and what people will do to survive.
