As someone who comes from a long ancestral line of people who talk to themselves while reasoning through problems - it would occasionally prove to be a minor handicap during proctored exams, as internal monologue isn't really the same thing.
Girlfriend, coming in from outside: "Who are you talking to?"
Me: "I talk to myself. You know that."
Gf: "Oh right. You also whisper to yourself, which is scary."
Me: "Scary?"
Gf: "It sounds demonic."
Which, to be fair... Evidently, my internal monologuing gets quite a bit vocal even with other people around.
He told me later he too does a lot of internal monologue for stuff as well and was told by some super successful businessman that this is a good thing and a hallmark of successful people so don't be discouraged by it.
So you may have to use the SLI bridge again just to make sense of what the other side is hearing.
