Meh
Don't ask me what's wrong, if I want you to know, I will tell you. Just leave me be for awhile. You may notice I am studiously avoiding contact with most people, because I've been feeling meh lately, it saves me and them the inevitable conflict when they ask what is wrong, and I don't feel like talking about it. Life will move on, things will get better and eventually my mood will turn around. Until then, MEH.
