My sister-in-law always sends me messages through my brother’s WeChat account. What does that mean? My sister-in-law’s WeChat ID is not hers. She also has a WeChat ID and posts to Moments every day.

1. Because they are husband and wife, your brother’s is your sister-in-law’s, and it is legal. Maybe post it on WeChat Moments to let people know that you already have a lovely wife at home, so don’t let people miss you.

2. Possessiveness is good. From another perspective, she cares about your brother. If your brother doesn't say anything, it's just a couple's internal time. People who have trouble with a small family must learn to let go.

3. I can see that your relationship as brother and sister (brothers) is very good. One day you will get married and start a business. Your sister-in-law is your brother's close lover who will accompany each other for a lifetime. You are your brother's closest blood relative. If he is not wronged, there is no need to feel wronged on his behalf. As long as your brother is aware of the big policies, the couple can handle trivial matters by themselves.
