My hair was used to be very long.I dreamed of donating it to sick children which had lost their hair. My teacher has donated her hair, so I wanted to donate mine, either. My dream came true last Christmas. After I told my teacher I was ready donate my hair, she praised me. Then we paid the visit to a hairdresser.The hairdresser cut 20 inch from my long hair and styled what was left. It was hard to say good-bye to my hair, so to help others made me feel happily. Now some of my friends are growing their hair long so that they can donate them this year.
