Well i do count to numbers usually that are even however, i do like the number five, because it's half of 10, and ten is a good number, some numbers scare me, as i trust even numers not odd numbers, though even some even numbers look wrong written down and i will avoid saying them in my head. I have a ditinct dislike for the numbers seven and nine. I do have other forms of OCD but counting tends to control the others anyway. Do you have anything else you do?
