What is the probability of sending an error message?

After using the mobile phone for so long, it was sent wrong, that is, the draft box sent the message quickly, and I didn't miss the other time. According to my estimation, he must have something to tell you, but he can't say it. He wanted to say it by text message, but he still didn't say it. I think you should take the initiative.

The probability of sending a text message in the end is very low, but it is impossible to send it to your mobile phone twice, brother, think about it.
