I think the purpose of this post is to gain emotional support. The author found himself in a situation he considered shameful. Situations where the phone rings unexpectedly are quite common, which can be explained by the fact that mobile phones are ubiquitous worldwide, and people tend to forget to turn off their phones, especially if they don't frequent public places where it's preferable not to attract attention. I would recommend the author consider this perspective: if the people who witnessed your mistake are good, kind, and civilized, they will understand and accept your mistake and forget about it immediately. If these people are petty, arrogant, and filled with the venom of contempt, you shouldn't fight for their opinion. Everyone is different, but it's worth believing that there are more good people out there, and it's worth thinking about them.
