Inside Marriage

Rupert and Elaine, young couple, got married and went happily on their honeymoon.
When they got back, Elaine immediately 'phoned her mother and her mother obviously asked, 'How was the honeymoon, dearest?'
'Oh, Ma,' she replied, 'the honeymoon was wonderful. So romantic...'
Then Elaine burst out crying. 'But, Ma, as soon as we returned home Rupert started using the most ghastly language... saying things I've never heard before! I mean, all these awful 4-letter words! You've got to come get me and take me home.... Please Ma.'
'Calm down, Elaine!,' said her mother, 'Tell me, what could be so awful?  What 4-letter words?'
Still sobbing, Elaine whispered, 'Oh, Ma...words like dust, wash, cook, and iron.'
