Whos That Woman Who Answered The Phone ?

One day, the mother asked the son to call the father,

who was on his overseas business trip,

to ask when is his plane landing at sg.

The son called and put down the phone a few seconds later without speaking.

The mother asked the son: "who answered the phone?"

The son replied : "a woman."

The mother was furious and locked up the gate, not allowing the father to come home

"mummy, why can't daddy come home?" ,asked the son

The mother said: "daddy has been sleeping with aother woman"

When the father returned home from his overseas trip, he was shocked at what happened.

"Don't think i don't know what you were doing at your so called 'overseas business trip'

"what?" replied the father confusingly

The mother said: "son, go tell your father who answered the phone"

The son said: " a woman"

"what did the woman say?" asked the father

The son replied: "The number that you have just called is not in use, please try again later."
