Avtar & Kartar used to stay in same building . Avtar on the Ground floor & Kartar on the 25thfloor. One day when the lift was not working, Kartar invited Avtar for a Dinner. Avtar trudged up to 25th floor to find Kartar's flat closed from outside and had a note which read : 'How did you enjoy your dinner ? ' Not to be outdone , Avtar wrote under it, 'Sorry , I could not make it .'
