Sometimes when I'm in boy mode, Steffi will be just beneath the surface and try to sneak out and get me in trouble.
Last Saturday I was at a neighbor's Christmas party. Someone introduced themselves to me, and I almost said, "Hi, I'm Steffi." Fortunately, I stifled myself just in time, and gave her my boy name.
Then on Thursday, I took my wife to the hospital for some outpatient surgery. The nurse came up to us and said, "Hi, I'm Stephanie, and I'll be taking care of you [to my wife] today." I almost replied, "My name is Stephanie also." Fortunately, I caught myself on that one also.
I'm sure that one of these days Steffi will be quicker than me and will out me.
