Rather than high pitched and girlish, my response is more likely to be mumbled and surly.Whenever someone says hi (or any other greeting), and I'm not expecting it, my response sounds all high pitched and little-girlish. Then of course, since I'm embarrased at how stupid I sound, I'm afraid to say anything else, which just makes the situation more awkward. Or if I'm in a social situation that is causing me anxiety, I'm focusing so hard on appearing calm, that I'll say the opposite of what I mean (for example: "hi" instead of "bye" or "you're welcome" instead of "thank you"). Does this happen to anyone else?
I don't do the "saying the opposite" thing, but if I'm a little flustered or anxious I'll double-up on my response - so I'll thank them twice, or say "Bye" followed by "See ya!" or something like that.
