A good friend

Mr. Smith was sitting in a train at a station one morning, when he overheard a man discussing with another man.
'Thanks for d weeknd Charlie, i rily had a great tym. Ur wife is a gud cook too', said d man.
When d man entered into d train and sat beside Mr. Smith, he stuck his head out of d window n said, 'hey Charlie, ur wife is a gud bed partner too', and slammed d window close. Shocked Mr. Smith askd d man sitting beside him 'mister, did i hear u spent d weeknd at Charlie's place, and that Charlie's wife is a great cook?' Sure, she is gud, answerd the man. Did i also hear u say that Charlie's wife is a gud bed partner? Wel, said the man, she is not; but u knw Charlie is a gud friend so i dont wanna hurt his feelins
