What are the reasons why girls don’t answer calls or text messages?

What are the reasons why girls don’t answer calls or text messages? There are two types: one is that you are really busy, for example, you are not holding your phone or hearing the ringtone, and the other is that it is inconvenient to answer any man's call when you are with other boys. That's too much. The most basic thing is that she is too lazy to pay attention to the person who is texting and calling her. It is also possible that she is playing games or working and studying, and her phone is on silent mode. I'm sulking or busy with something. This straight woman usually does it because something happened or she didn’t hear her. There are three reasons: 1. I don’t like you and I’m too lazy to reply! 2 didn’t pick up the phone, 3 was quite busy and saw the call but didn’t have time to answer it!
