I use the chat bubbles to RP my main character. As he is blind, I turn off labels, but since with his senses he can determine certain things, he can tell where a person is if they make noise. But he can only tell -who- a person is if they speak. So I have labels off and chat bubbles on. When I see a chat bubble above someone's head, and I see it is someone who I know who said it, then I now know they are there and where they are. BTW, this is why I might walk right past someone IG without stopping unless they speak :/
