Whatever you give a woman, she's going to multiply.
If you give her sperm, she'll give you a baby.
If you give her a house, she'll give you a home.
If you give her groceries, she'll give you a meal.
If you give her a smile, she'll give you her heart.
She multiplies and enlarges what is given to her.
So--if you give her any crap, you can expect a ton of shit.
