No, no, no. The less you say the better. Stoney silence is the right demeanor. Lose the word "upset." The correct stance is furiously angry. You are a person who has trouble feeling angry. Flex your anger muscles. Humans are supposed to get angry over some things. You want to make this whole unpleasantness be over as soon as possible. No. You need to drain this experience to the dregs, or it'll just be the first in a long line of such experiences.

Stop positioning yourself before her as the supplicant. It makes you look unsexy. You want to talk this thing to death as soon as you can get ahold of her. Let her do the talking. Let her worry about what to say.

There are times when being angry, sullen, brooding and silent is exactly the right way to be.
