I usually use a specific spoon when eating. Or if I'm at a different place, I make sure the spoon and fork matches, neither is bent/crooked and must be stainless steel.

I skip one a step on the stairs. So I usually step on the even numbered steps.

I always make sure that my right feet touches the ground first whether walking, climbing stairs (esp the stairs) or running.

I always close the doors of our house, especially if I'm all alone. I don't like getting disturbed.

I always make a face when I dislike doing something (my lips are bentupwards, almost touching the nose) followed by a long, high ptiched 'hmph'

I always do a 'ninja hand sign' everytime I want to do something.
