Three sisters aged 82, 84 and 86 live in a house together. One night the 86-year-old draws a bath. She puts her foot in and pauses. She yells down the stairs, “was I getting in or out of the bath?”.
The 84-year-old yells back, “I don’t know. I’ll come up and see”. She starts up the stairs and pauses. Then she yells, “was I going up the stairs or down?”.
The 82-year-old is sitting at the kitchen table having tea listening to her sisters. She shakes her head and says, “I sure hope I never get that forgetful”. She knocks on wood for good measure then yells out, “I’ll come up and help both of you as soon as I see who’s at the door”.
