What does it mean to send a text message to apologize after quarreling with the leader, and the leader does not reply to the text message?

If you have an argument with the leader and then send a text message to apologize to the leader, but the leader does not reply to your text message, there may be several possibilities:

1. The leader is still considering how to reply to your message, and it may take some time to think calmly and deal with it.

2. The leader may have read your message, but he doesn't know how to reply, or he is still hesitating to reply.

The leader may not accept your apology, or think that your behavior has caused harm, so he doesn't want to reply to your message.

In either case, you can consider waiting for a while before trying to communicate with the leader. When communicating, try to be calm and polite, and express your apologies and willingness to fix the problem. If the leader still doesn't reply, you can consider seeking other ways to communicate with the leader, such as face-to-face communication or writing a formal apology letter.
