Thanks, wanderinggrl. I've added, "I don't know," and "I don't know - I need a couple of minutes to think about that" to my list of phrases to try. I just thought of another one - if the person makes a statement (instead of a question) that takes me by suprise, I could say, "Wait a minute. Would you please repeat what you just said?"
Do any of you have any tips or tricks for remembering to say what you planned to say rather than automatically falling into old patterns? I suspect that role playing (i.e., behaviour rehearsal, not gaming) would be the best thing for this, but are there alternatives that are almost as good?
This isn't directly related to my original post, but has anyone here ever recorded some of their conversations? I know that this might be a creepy (and possibly illegal) thing to do without the other person's permission. I might ask someone I trust if I could record our conversation to listen for tone of voice (his/hers and mine) and the timing of the conversation. I recently saw myself on video (completely candid footage as I did not know that we were being filmed - I was part of a tour group and someone made a souvenir video for us) and I thought I moved my head in a strange way - I stood out as a bit odd, even to myself!
This and some other recent events have made me realise that I am not always aware of how I move, sound, and look (especially facial expression). I've always suspected I'm a bit "different" but until quite recently I was not aware that I might be more than just a little bit different!
