Brain, I understand you're trying to help me by injecting more hormones into my body when I feel happy because you think the chemical balance is wrong but hey! Would you mind not doing that so much because now you've put me on an unjustified downer and that ain't no fun. I was enjoying that carefree feeling last week; I would understand if something negative had happened thus making me feel depressed but no, nada, nothing.
Don't forget you're in my skull therefore you belong to me and you should do what I say. I don't want to have to stage a strike ok, that's no good for anyone.
