Here's one...
Mr Kubrick is an old man who needs a walking stick to walk with. He lives in a high-rise apartment on floor 30. He wakes up in his bed one day, gets up and has a cup of coffee. He opens the kitchen cupboard only to realise he ran out of bagels. In a bad mood he pulls on his jacket, leaves his apartment and walks towards the elevator. Once inside, he pushes the ground floor button and the elevator starts to descend. Once he reaches the bottom, he steps out of the elevator, walks across the lobby and leaves the building. He crosses the road, and enters the bakers opposite the bank on 3rd street. He purchases three sesame seeded and one plain bagel. He then walks back down the road, across the street and back to his apartment block. He walks across the lobby towards the elevator and presses the call button. Now he could smell the freshly baked bagels in his bag, his mood became happy and he couldn't wait to get back to his apartment and eat them. Even the 5 minute wait didn't spoil his mood. Once it arrived he got in, pushed the button, and the elevator started to ascend. "Great, no-one else needs the lift" He thought to himself as the lift rose upwards. Floor 18, 19, 20 all went past quickly and the elevator came to a smooth halt on floor 21. Mr Kubrick then hopped out of the elevator and headed towards the stairs and walked slowly but surely up to the top. His mood faltering as he climbed the long staircase up to floor 30. When he finally got back to his apartment, he was too tired to eat and instead, went to lie down on his bed, where he fell asleep again...
Why didn't he take the elevator all the way to floor 30, saving himself from getting all tired and being unable to eat his beloved bagels?
