The description of Richard’s stone as “the size of a human skull” reminds the reader that Richard was just trying to dig up Rachel. Richard’s shock at seeing Patricia laughing with a Black man reminds the reader both of his racism and his exclusion from the human connections that humor provides. Notably, when Richard betrays his dementia by asking whether they’re dead, Looksmart reacts with “a sound like laughter that is not laughter”— suggesting that what Richard said might be morbidly funny, but that Looksmart won’t even laugh
at Richard, let alone with him. Richard’s fear that the house is burning down may symbolize Richard’s loss of the past to dementia or his fear that historical change has irrevocably destroyed past social structures that benefited him, such as white supremacy.
