Women are so hard to please

Soon after my wife and I met, she mentioned how she really wished that she could afford a riding lawnmower. She was a single gal that worked all day and was often tired in the evening when she got home from work. So, being the handy sort of guy that I was, I made her a riding lawnmower. I guess I thought she would squeal with delight and give me a big hug. Instead she just stared at it. To this day I have never been able to understand why women are so hard to please.
