Dear Kate,
I’m worried that you’ve been addicted to share pictures in WeChat circle recently. You even share all sorts of photo in your daily life. Of course, WeChat makes better to understand each other and makes our life more colorful, through which it is very convenient for us to communicate with. However, there exists some potential risks if we overshare. One severe problem is leaking privacy, that may cause economic losses. Besides, oversharing can make others uncomfortably, for they think you are showing off.
Thus, never should we post our personal information, nor should we blindly add strangers to a list of friends. It’s much wise to set aside some time to accompany parents or do something more meaningful, such as reading books and taking exercise.
Yours,
Li Hua
