I remember the first time I got on a horse. I was two years old and we were watching a friend of the family ride. My mom agreed to let me take a short ride around the ground with the friend and that was it' I became crazy about having a horse. From then on, I drove my parents mad begging for a horse. Whenever I saw a horse, I would beg even harder.
When I was four years old, problems appeared in my life. I had Selective Mutism(选择性缄 默症). This is an unusual childhood disorder(失调)in which children stop speaking in certain social situations, many times at around the age of four. I spoke to my parents as usual, my brother and certain other people, but was silent at school and in social situations. I went days, weeks, months without a sound at school. At most, I might very quietly speak to a friend.
My parents looked for a cure. One psychologist(心理医生)had an idea. Having discussed his plan with my parents in advance. one day I was asked by the psychologist what I wanted more than anything in the world. He explained that I was going to be given a chance to work for what I wanted. I couldn't believe my good luck, but I could not answer. I just stood there. Finally, I was allowed to whisper(低声说)the answer in my mother's ear. "A horse," was all I could say.
I was to get a little horse, but before we could even start looking, I had to try to talk. I had a chart of weekly tasks I had to finish. I had lo answer the phone five times every week, something I had never done before. I did everything that was asked of me and the day came when my parents found the perfect horse. His name was Sequoia, a strong little chestnut(栗子马). He was perfect , of course, and I fell in love immediately. It truly was a dream come true. When I was with Sequoia, I forgot all about my problems and felt strong and life.
By connecting with them, I have learned to hug what I was once not able to do and I found my voice back.
