Victor, and old friend of the family’s, came over one day and as usual he didn’t know who whom was, as he asked each of them one question.

Victor asked the sister that was sitting on the left, “Which sister is in the middle of you three?” and the answer he received was, “Oh, that’s Asha”.

Victor then asked the sister in the middle, “What is your name?” The response given was, “I am Usha”.
