Why do some girls in the class usually don't talk to you at all, but often send you short messages … Why …

Most girls are silent in front of people and open in front of the internet. It is more casual to express yourself by SMS. For example, I don't usually talk to boys in my class. At most, I will say hello to a few people I know very well, but it will be much more casual on the campus network. This is why the network exists.

Don't be surprised, because in my eyes, boys seem to be like this ... hehe.
