I have an adjacent problem. I'm always worried I'm coming across more forceful and authoritative than I mean, so I sometimes feel compelled to follow statements or short conversations with "at least, that's what I think/assume is going on, or is the only thing that makes sense to me" to make sure people are aware they are getting my opinion or educated guess. I like to pontificate and work through solutions out loud with the person asking (a habit that runs in my family) when a question is asked that I don't know the answer to, and I suspect my thoughts in verbal form may be taken as assertions of fact when that's not the purpose.
