In junior high school, I often went to Shanghai Luwan Library (now renamed Mingfu Library) to read books. This library has three floors, and there were more students there, especially during the time before exams. One weekend I went there to study. The third floor was the least crowded and the quietest, but it was also very crowded at that time, so I shared a table with a student couple. They were obviously in love, and they were constantly making intimate gestures. They may be high school students, the girl is not a big beauty but very innocent and fair-skinned. I was in my second year of junior high school and was at an age when I vaguely understood the things of men and women. While reading a book and secretly glancing at them, I was also slightly excited. Their movements were so small that they did not attract the attention of the people around them, but I could see them clearly. I pretended to drop something on the floor and peeked under the table (there was a very large wooden table placed over there, and the table was open underneath). With just a glimpse I saw the boys putting their hands on the girls’ thighs and caressing them. I was afraid of being discovered by them and did not dare to look more. Red face continued to read, after a while they whispered to each other a little side to talk and laugh to go to the bathroom. The bathroom on the third floor of the Luwan Library is a very simple two compartments, I naturally know that I have been there many times. After a while they have not returned, I looked around and no one noticed me and went there. The heart was in a state of flux. I walked to the bathroom and saw that the door of the cubicle (leaning in) was closed against the woman, and I vaguely heard a sound inside, I walked gingerly into the other room, and felt that there was a vague metal sound of the belt buckle hitting next door, and from time to time there were girls who did not hold back their laughter, and I was tickled, and I was afraid that others would come knocking (because at this time both rooms were closed), and I stayed there for a while and walked out, pretending to wash my hands to try to calm my mood. I stayed there for a while and went out, pretending to wash my hands to try to calm myself, when someone came over, I went back to my seat. It took ten minutes for the couple to return to their seats, with the girl holding the boy in her arms, both of them with flushed faces. Now, years later, I can still recall the scene and imagine their intimate actions in that humble cubicle.
