At least that's what my coworkers tell me. I'm not sure if it's a good thing or bad thing.
Part of my work involves the phone -- lots of calls. One customer in particular started the discussion. She had me on the phone for a while, and was telling me about their latest problem du jour. Apparently, I said, "oh no!" about 14 times in the course of the conversation.
I also said "Whaaaat?" one day and it sounded like a chicken's "bwaaak!" I won't even cover the other things we discussed (suffice to say that my coworker asked first if our lone male presence was in the room)!
I laughed until I cried. It was a great stress reliever.
But then again, they also said, "Please don't change being so expressive!" That's me, that's me, Comic Relief at your service!
