①An old gentleman whose eyesight was failing came to stay in a hotel room with two bottles of wine in hand.
②On the wall there was a fly which he took for a nail.
③The moment he hung the bottles on,they fell broken and the wine spilt all over the floor.
④When a waitress discovered what had happened,she showed deep sympathy for him and decided to do him a favour.
⑤The next morning when he was out taking a walk in the roof garden,she hammered a nail exactly where the fly had stayed.
⑥Now the old man entered his room.When he looked up at the wall,he found the fly was there again!He walked to it carefully and slapped it with all his strength.
⑦on hearing a lond cry,the kindhearted waitress rushed in.To her great surprise,the poor old man was there sitting on the floor,his teeth clenched and his right hand bleeding!
