My kindergarten teacher usually referred to herself in the third person, and I was about three weeks into school before I figured out she was talking about herself. "Now, Mrs. F. is going to leave the room for a moment, and she is going to be very disappointed if she comes back and finds out that children have been goofing off."
I didn't know who this woman was, but she terrified me, and I was counting on my kindergarten teacher to protect me from her.
