I have never heard of Sedaris, but, if The Dowdy One likes him, I get an idea of what he considers a "normal family life."
David Sedaris is a writer of humor. He's actually pretty funny but you have to overlook a lot: he's openly gay and lives with his boyfriend in France and used to do occasional commentaries on NPR. In his book ME TALK PRETTY ONE DAY, he described his mother's hobbies as 'smoking and napping'.
David Sedaris is an author who often writes about his very bizarre family life. He's very funny, but very "blue state." His sister, Amy, is also hilarious -- she starred in "Strangers with Candy" on Comedy Central. Very weird but funny.
He's gay. That should tell you all you need to know.
