I used to have this problem and I’m not sure exactly how to fix it but I can say that it helps a lot if you consider what potential responses you might get before you speak. Don’t just say things because you want to say them, say things because they open up the conversation for interesting responses. This is not the same as “asking a lot of questions” because that’s exhausting, as anyone who’s dealt with a Sealion knows. Instead, try to say things that are open-ended. If your chat’s tone is comedic, try not fixing your typos so that someone else can chain a joke off of them. If the chat’s tone is serious, try making an analogy that connects the current topic to a previous one. If the chat’s tone is toxic, you can leave.
