Not for Love nor Money

For years, my wife has been asking me to dg dancing with her. I'm a terrible dancer and would never go, not for love nor money. However, last week was my wife birthday,so I decided to surprise her with a one-hour dance lesson. As much as I hate to dance, I did not have the heart to tell her we couldn't go dancing. I didn't want to make her unhappy.
I found a dance studio near the International Center and made an appointment. At first, I didn't want to go. My heart wasn't in it. But it was my wife's birthday and I wanted to do this for her. I'm head over heels in love with her. I was really afraid if I didn't take her dancing after all these years, I would have to kiss my marriage goodbye.
The istructor at the dance studio was very nice and showed us some steps. I was really trying my best to learn the moves. Before long I was dancing my heart out and spinning my wife around the room. The instructor told me I was doing great, but to be honest, I don't think she had the heart to tell me I was the worst dancer she had ever seen. "Take heart," she told me. "You're doing great!"
For one hour, we danced till our heart's content and had a great time. I only stepped on my wife's feet a couple of times. She told me that this was the best birthday of her life an that I have a heart of gold. Even though the dance lesson was a labor of love for me, I had a better time than I thought I would, and would even consider doing it again. Honest. Cross my heart. I'm not just saying that to kiss up to my wife. Dancing is not so bad as I thought it would be. Eat your heart out Fred Astaire!
