What short messages are there in your mobile phone that you can't bear to delete?

I feel that this kind of short message is rare, and it is basically a short chat record with good friends and parents.

After I went to college, I usually received harassing text messages from various software, as well as verification codes and reminders of various express delivery, as well as a large number of mobile phone traffic reminders. Because after going to college, people of this age rarely communicate some unnecessary factors through SMS, basically using QQ or WeChat, and more importantly, making phone calls directly.

So there are very few text messages. However, SMS basically doesn't take up too much memory, and it is basically emptied every once in a while.

But I have a good friend. In high school, we often communicated by SMS, because although we said we needed a mobile phone at that time, we basically didn't need QQ to communicate, and QQ communication was not very convenient at that time.

So SMS has become the only means of transportation for us to maintain our relationship. We all communicate by SMS, and so does any news.

When we miss each other, we will write a paragraph on a short message. I remember that my composition level has improved a lot because of this short message. Even now, those short messages are still preserved, which is a testimony of our friendship. Every time I read those short messages, I will have many good memories.
