Innocent daughter-in-law?!

The newly-married daughter-in-law demurely told her mother-in-law, "Mum! I want to know about the customs here."

The mother-in-law said, "Yes Yes, go ahead!"

"How many months after marriage are babies delivered here?" the daughter-in-law enquired.

"Why ? after nine months," told the mother-in-law, struck by her daughter-in-law`s innocence.

"But," declared the daughter-in-law, "At my father`s place, they do it after six months, and for the first time, I shall follow their custom."
