Why Such Long Hair?

I met two boys, one Japanese and the other Korean, who had very long hair. The Japanese boy was in elementary school. Actually, I thought he was a girl when I first met him because of his hair. When he entered junior high school, he cut off his long hair and looked like the other boys. I met the Korean boy when he visited Fujimae Tidal Flat last December. He was a junior high school student, and his hair was even longer than the Japanese boy’s. I met him again when I went to Korea last week. This time, his hair was short like the other boys’. Why did these two boys grow their hair so long and then cut it short? They wanted to help other people who had lost their own hair, so they grew their hair long, cut it short, and made a hair donation. (148 words)
