Mom is 50 years old. What should I do if I see someone sending her an ambiguous message as a son?

Then tell her clearly, but don't say it directly, she will be stimulated. You'd better give an example or make up a story that your friend is having an affair, and the result is very bad. Don't be too direct, it will save the influence on your relationship, but having an ambiguous text message doesn't necessarily represent what your mother is like. If she hadn't been like that, she wouldn't have gone downhill. Of course, you should also consider that your mother may be very. Therefore, it is normal to send some boring text messages. Just say it politely after the investigation is clear. Mothers generally care about their position in children's hearts, so you'd better speak out and don't disturb others!
