When I change the volume on my TV, I have to have it at an even number or a multiple of five.
If the volume is at, say, 19, I have to put it to 20, even if 19 is perfect.

for me its not too big of a deal, but i like it to be a multiple of 5. like if someone turns to volume to 33 i just turn it up two or down two.
i have suspected that i might have slight ocd though. not to the point that i would need therapy or drugs or its taking over my life, but i do have my things like making sure numbers are even and stuff.
i think its fine, as long as youre still happy and its not a big deal and youre not constantly doing things like this.
