Parks has her fixations -- Abraham Lincoln (he lived to age 89!); arms that are frozen before the knife can kill; racial injustice; literalized metaphors (an actual Window of Opportunity that actually closes shut); stage directions that can never be enacted; playing possum; plutocracy ("The Presidents Day Sale"); asshole warmonger dictators -- but it's interesting to watch her ring her themes' changes.
Many plays are startling and compact, with topics like watching over a sleeping stranger as an image of compassion ("The 1st Constant"); spoofing Neil Simon ("Barefoot and Pregnant in the Park"); Bush murdering his own soldier and calling it "poignant" ("House to House"); mothers protecting and relinquishing their children ("Behind the Veil of the Goddess"); breaking the cycle of poverty and crime ("My Father Was a Famous Mother"); women and men always failing to get along ("Epic Bio-Pic," "Vase" and "Bear"); depicting suicidal despair and its cure ("Plenty"); and ridiculing sectarian war ("Everybody's Got an Aunt Jemimah").
Some plays overlap; some plays interrupt others; and some of Suzan-Lori Parks' plays stretch people's minds out to infinity.
