Pillow

This morning, there were many students on the train. It seemed that their summer vacation has ended. A girl sitting next to me kept dozing off and leaning on me. Sometimes she woke up and straightened up her posture, but soon she learned on me again. At first, I could tolerate it for a few minutes, but after more than thirty minutes, I started to feel uncomfortable. My shoulder isn’t a pillow. I was really relieved when she finally got off the train.
