The doctors told us my mom might be saved with surgery. But it could also kill her. She chose to have it. The day before the surgery I was off school, and my mom planned the best day of my life, everything I loved at seven and everything that would put a smile on my face. The day began with her waking me up saying, "Kate, I have a surprise for you. Come and see." The surprise was a doll I had wanted for the longest time. Throughout the day, she told me everything that she thought I would need to know to grow up and be a good person; she told me to be the best I could be and that I would always make her proud. We had a picnic in the park, and it was so cold that we moved to the car. The day was filled with laughter. For the first time in a long time I could see she was really happy. I would never forget her smile, or the way her eyes shone as if we were the same age. It was the best day of my life, and I will never forget the conversations we shared. My mother managed to live through the surgery. Now when I look back, I realize that the best day of my life could be her last and this could be the last day I would remember with her, the last one we shared.
