The novelist Tom Perrotta is 60 years old, a long-married father of two grown children, and a resident of suburban Belmont, Massachusetts. He’s an uncool man at an uncool age living in an uncool town. He has wasted no time with high-profile literary feuds. He has punched nobody, has neither canceled nor been canceled, and doesn’t bother with social media. (The only Tom Perrotta on Twitter is the late, very good tennis journalist.)
