Sad memories

I just had to take a picture of these Flamingos. When I was in the first grade, I took art lessons from Mrs. G. I really enjoyed going over to her house and playing in all the colors.
Anyway, it was the end of the year and I had my masterpiece. It was a painting of a flamingo. I remember the compliments that Mrs. G gave me. I could not wait to enter it into the local art show. There was no way I was going to lose. That last day of class I signed my work just as every other artist in this world does.
Well the show was a few weeks later and I did not place. I could not understand why. How could such a beautiful and colorful painting(by me) not win first prize, especially when everyone was telling me how great it was. Then they filled me in and told me that it was my signature. Apparently, it was to go on the back or even on the bottom right, but not in large letters between the flamingo's legs.
After that I never painted again.
