I'm obsessed with the numbers 227 and 212...not sure why. I use to add, multiply, divide, subtract numbers that I saw in different places-addresses, telephone numbers, sequential lisense plate digits, whatever-especially if the sum, product, difference at the end or beginning is in the last or beginning place.
I walk in the center of squares in floors or on the sidewalks.
I have to rinse my face 20 times in the morning... I just have to... Or I can't leave the house.
On the tv, the volume has to be at even numbers. On the microwave, I use increments of 5.
I'm not sure if that counts. I was never diagnosed, yet I never told anyone about it. It doesn't disrupt my life...it's just rituals here and there.
