This truly happened in an advanced oral English classroom:
When the teacher asked the students: “What surprised you most in Tsinghua?”
One of them answered, “Well, I’d heard that girls in Tsinghua were terribly ugly before I came here. However, when I arrived here myself, I was surprised to find
there’s so many pretty girls, some of them are even sexy……”
At that, all girls in the room smiled shyly. Then he continued, “But when the holiday was over, I found all of them had gone!”
