Description of purchasing SMS

A boy often buys things and sends messages to girls. This signal is very clear, that is, boys like girls and want to chase her. However, when the boy worked hard for a period of time, he found that the girl had nothing to say to him at all, but she had to sign for the boy's things and didn't reply. This is not special. Send messages to girls and don't answer them. After a long time, it is normal for boys not to send text messages. Because of hopeless efforts, no one will try foolishly again, so they give up decisively.
