A girl's perfunctory chatting style may include the following manifestations:
1.*Short Reply**: Reply with only one or two words, such as "um", "oh", "okay", etc., without expanding on the topic or providing more information.
2.*Delayed Reply**: Replies to messages that take a long time, or are only replied to once at long intervals.
3.*Shift Topics**: Instead of responding to questions or topics you ask, you suddenly move on to other topics.
4.*Lack of emotional expression**: Lack of emotional engagement in chat, not expressing feelings or opinions, and appearing cold.
5.*Repeat Answer**: Use the same reply over and over again, such as "haha", "uh-huh", etc.
6.*Don't ask questions**: Rarely initiate questions or show interest in your life.
7.*Emoji is used more**: Emojis are used a lot in replies, and text is used less to communicate.
8.*Cold tone**: The tone appears cold, perfunctory, and lacks enthusiasm and positivity.
It is important to note that these performances do not necessarily mean that the girl is necessarily perfunctory to you, and there may be other reasons for her way of replying. If you're confused or unsure about her response, it's best to communicate with her directly and ask her about her thoughts and feelings to avoid misunderstandings.
