I needed a new car and I asked my mother to lend me some money so I wouldn't have to ask for credit at the bank. She said yes and came with another proposal, she would give me the money if I would came had have dinner and spend the night with her every week days during two months. It was a good deal, I didn't have to pay her back, I had free dinners during the week and sex. But after a few days I realized it wasn't that easy. After I day's work I came home and my mother was already in bed waiting for me and only when she's completely satisfied I'm allowed to have dinner and go to bed.
