What does it mean that a girl always doesn't answer your phone and replies to a short message for a long time?

Oh ~ that depends on your relationship with her.

According to my analysis:

If you are boyfriend and girlfriend, there are three possibilities: ① she may be married; 2 she is convenient; She is doing something indescribable.

If she is an ordinary friend: ① she is chatting with others; She is busy with her own career; She doesn't want to show her tone.

If it is a colleague or a junior: ① She has an appointment with a beautiful woman; She is playing a game; She is taking a bath.

If it is a netizen: ① she is playing mystery; Maybe she is a stingy person; Maybe she is not herself.
