You don’t always have an answer to a text right away. You may need time to think, especially if your friends asked you something very serious. You don’t want to ignore your friend, so you send them a thinking emoji instead. That shows them that you’ve read the text, and don’t want to leave them hanging. You’re putting a lot of thought into your response, and you don’t want to reply too hastily. With this emoji, your friends will know you’re taking great care in replying to their text. You want to think everything through before you make a decision.
