What's immoral about stealing other people's socks?

An incredible thing happened in a residential area of Qunxian Road, Lianhu District, Xi City, Shaanxi Province. The community owner found some anomalies in the online surveillance video. It can be seen from the monitoring that a man came to someone else's shoe cabinet in the corridor, then picked up his shoes and socks and put them in front of his nose and began to smell them.

Stealing other people's smelly socks is not something that ordinary people can do. Can be described as abnormal. Fortunately, a nearby monitor caught this scene. If there is no monitoring, no one will find this person's behavior, but no one will find that he may do more unexpected things next.
