@Oblivion77 Since this comment seems somewhat decisive let me say this, I am calling this person a bi*** for horribly misrepresenting ocd, and claiming they have ocd. About 96% (It’s hard to find a recent study on how many people claim to have ocd but but, so I decided to round the number down to give the benefit of the doubt) of people who claim to have ocd don’t have it. Wanting things to be a certain way is not ocd, it’s human nature. Ocd is when if things aren’t a certain way you get physically ill or start hurting yourself (not intentionally), and all around heavily impact your life, not; ‘ugh I don’t like looking at this as it can be more even and would be so much nicer if it were even’. Another thing to consider is that ocd isn’t as clear cut as even numbers > odd numbers, for most people with ocd a specific number just does it for them and is perfect and everything else is the same, and it doesn’t necessarily need to make sense, it could 9 or 11 instead of 10 despite 10 being right there and being a nice number that’s both even and a multiple of 10. Ocd can flare up due to a number being odd yes, but as the number gets bigger that becomes less and less of a factor. By the time you get to the 70s most people’s with ocd favourite number in the 70s will depend on what their comfort number is primarily, so someone whose comfort number is 9 will likely have either 72 (7+2=9) or 79 (7 and 9) be their favourite of the available numbers, but aside from those numbers, a balanced number (66, 77, 88, etc) is more likely to be favoured.
