Old Mrs. Pierpoint
Because she hasn't heard anything from her for a few days, a woman is worried about an older woman, a widow, who lives in the apartment next door.
So she tells her son, "I want you to go next door and see how Old Mrs. Pierpoint is."
A few minutes later, the boy returns.
"Well, is she all right?" the mother asks.
"She's fine, but she's annoyed with you," he says.
"At me? Whatever for?"
"Well," says her son, "Mrs. Pierpoint told me it's none of your business how old she is."
