I chat with my girlfriend by SMS, and some of her messages always add some punctuation marks before and after, not that kind of expression!

I guess your girlfriend is born after 90.

In fact, there is no specific meaning. Sometimes periods replace ellipsis, and then they are typed out habitually. Sometimes ellipsis is a word that replaces two people.

Because I often use a period, I think it is a habit to use it in the future.

Symbols with emoticons are mostly abbreviated versions of QQ emoticons like [Laughter] [Joy] [Tears] [Sadness] [Chop Hands]. For example, when I type the word "uncomfortable" on my mobile phone, an expression is ≥≤ ... Do you think it looks like it?

This expression is similar. . .

I hope you and your girlfriend are getting better and better ~!
