I sent a short message to the leader by mistake.

Send short messages to leaders by mistake:

If the text message is a blessing greeting, don't pay attention to it.

If the content of the message is a personal problem, you should immediately resend a message or call directly to explain it.

If the message contains disrespect for the leader, you should not only explain it by phone or text message immediately, but also explain it in person. If possible, please ask the leader to have a meal to make amends.
