Three sisters of age 92, 94 and 96 live in a house together.
One night the 96 year old draws a bath, puts her foot in and pauses.
She starts up the stairs and pauses, then she yells, "Was I going up the stairs or coming down?"
The 92 year old was 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.
She then yells, "I'll come up and help both of you as soon as I see who's at the door."
