If you feel that the chat is getting boring or less interesting, you can always pump it up by asking questions. As observed, questions generally keep the conversation engaged. Ask directly about them (not yourself), any situation or as low as “What are you doing right now?”. Also, it’s important to appreciate the replies you get (even if they’re none of your business). This is because appreciating each other for even tiny things are important and presents that you really care about them.
