I sent a text message to the girl I just met, but she didn't reply. What should be the reason? What should I do?

First of all, some people don't reply to funny news. They don't think they need to reply to them, but that doesn't mean they are unhappy when they see them. They like them too.

Your purpose now is very clear. You want to chase her. Then there are two options. First, you can ask her to meet. For example, you can go to her school, which means you will visit her school. Then you can just tell her that you like her and hope that she will give you a chance to ask her if she has a boyfriend. Second, more time is needed. Don't send her funny messages. Send her a chat, care or ask questions. It is better to include questions at the end of the message. In other words, under normal circumstances, if she receives it, she should reply. If she does, you can often send her such short messages, and you will be affectionate for a long time. Don't tell her when you think the time is right. If she doesn't answer, you can use the first one and tell her directly.
