I remember that there was a very awesome little kid in the courtyard at that time. He could always swallow back the saliva that was about to fall on his chin. This was not his unique skill. Once I saw that his nose was running continuously, and it was almost touching the ground. With a whoosh, he sucked back all the breath. I have admired this for a long time and have been practicing this unique skill for a long time. Unfortunately, my nasal mucus is not sticky enough and it breaks every time it reaches my neck.
