Three sisters ages 92, 94 and 96 live in a house together. One night the 96 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 94 year old yells back "I don't know. I'll come up and see". She starts up the stairs and pauses. "Was I going up the stairs or down?"
The 92 year old is sitting in the kitchen having tea listening to her sisters. She shakes her head and says "I sure hope I never get that forgetful". She knocks on the wooden table 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."
