What should I do if I find that the boss's wife of a superior supplier is having an affair? The ambiguous message was sent to my mobile phone by mistake!

One is to turn a blind eye (forget to read the text message).

Another way is to buy a new number next time, tell the superior supplier that you have changed your number, and give them a new number again, saying that the old number is useless, provided that you haven't had your phone contact list for a while (if the boss accidentally left you a message on your mobile phone, don't you feel wronged when the boss finds out it's your number? )

In this case, your performance should not be understood as "discovering other people's extramarital affairs", but simply as "what message did your friend send wrong"

Don't want to get some benefits just because you know other people's secrets. This situation has no steps, and it will only increase your own troubles and others' troubles.
