I'm wondering who else is like this. I notice that when I have something and it's not divisible by two, it irritates me badly. For example, I have 10 cigarettes, smoked one now it's nine. So, I immediately smoke another one to make it an even 8 (8 divided by two=4). It's an OCD thing for sure, but who else here can't stand odd numbers?
I dislike odd numbers and if I can I might try to make it even somehow, but I'm not super OCD about it. I can still sleep at night if it's not even.
I have this same issue with numbers. I like even ones, given my choice. (Thought about putting it in the 5 things about you thread). I've only driven cars from even years. I've lived in places with odd numbers, though, and somehow it didn't bother me, so it worked out.
Smoke another cig just to make it even? Nooo. Honestly I don't count my cigarettes. I noticed a while ago I was going a bit off the charts with my cleaning and ordening and developing ocd like habits, so I stopped counting things and "leave things as they are". When I did see the number by accident, I forbade myself to change it. Sometimes it drives me nuts, but I try to distract myself by doing something else. Works for me.
I don't know if I may be alone but sometimes I like to count out phrases and sentences that I hear and I edit the sentence so that it is divisible by 4 or 5 and is either 15 or 20 letters long. I never tell people this, though. Not sure if this is a mark of OCD because I don't do it obsessively, but I do it everyday.
