A man bought a new pair of trousers for his primary school mates reunion dinner. When he tried out at home, he found that the trousers were too long by 10cm. He asked his mother to help him shorten the pants. His mother said she could not do it as she was not feeling well and would like to rest early.
So the man approached his wife to shorten his pants. His wife said she was very tired and had a lot of work to do that night, so she could not help him to shorten the pants that night. Then the man asked his daughter. His daughter apologized for not able to do it that night because she had agreed to go dancing with her boyfriend
“Ah well!” The man thought and decided he could wear his old trousers to the reunion.
Later that night, his mother thought to herself, “My son has been very nice to me. I’ll just help him to shorten his pants before going to rest.” So she shortened the pants by 10cm.
