Ratio Intolerance

It's a problem I've had since I was a child. Whenever I got a bag of M&Ms or Skittles, I immediately dumped them all out and separated them into piles by color. Then I would even out the piles by eating the extras. After I had perfectly even piles, I would eat one from each pile (in rainbow order), always careful to maintain an even ratio, until all the candy was gone. I've done this for as long as I can remember, and it never seemed strange to me until I met Rick.

Rick requested that I bring a meat, cheese, and cracker tray to our small group one week. I did, and in true Becky form, there was a perfect ratio of 1 meat:1 cheese: 1 cracker. That's just good sense, right? But then Rick did the unthinkable. He made a sandwich! (cracker/meat/cheese/cracker) I didn't want to make a big deal about it, so I quickly scarfed down a piece of meat and a piece of cheese. "There", I thought, "All fixed". Then he did it again, and he wasn't the only one! I sat there all evening keeping a mental tally and trying to eat up the difference. Needless to say, by the end of the night, I was sick, and my small group was more than a little concerned.
What is wrong with me?
