The sound of corduroy

My brother and I walked to school together everyday. I hated the cold weather and part of it was that my brother wore corduroy knickers(pants that came just below the knee).His socks were knee high and met up with his pant bottom. the corduroy made a very annoying sound as the pants legs met as he walked along. I hated that sound. I would tell him to walk ahead of me or behind me to avoid hearing the noise it made. Since I was the older sister, I was suppose to be holding his hand when we crossed the streets but I would send him ahead.
