What does it mean for girls to reply to boys' text messages in seconds?

There are two situations for girls to reply to text messages: First, they are just using their mobile phones, and reply as soon as they see the text messages. This situation has no special significance, that is, the timing is just right; If a girl replies every time instead of once, there is no doubt that she has a good impression on boys, which shows that girls care about boys very much, always pay attention to boys' movements and reply as soon as there is a text message. If you have a good impression on each other, you care about their feelings. The behavior of "second return" reflects that you are very kind to each other and don't want them to feel left out.
