clean garages might go along with a single woman's new town home. Not much in the way of tools or machinery, exterior maintenance supplies, even lawnmower required...
portion-controlled home-cooked weekly menu of food in containers might go along with a strict diet regimen.
organization is a good thing, I think.
I don't think any of the above, points to OCD per se.
Gosh my mom is soooooo clean and neat and organized but ... that is just her way. She's also slow & careful, thoughtful and meticulous. We tease her, but what a comfortable clean, organized and welcoming home us 5 kids grew up in!

Me, too. I don't find it obsessive that she "carefully wrapped" and returned his picture to him. Maybe it was one of his favorites from something special in his life. It's not unusual to return things to ex's.
As far as the clean garage floors, so? One of my BFFs keeps a house that looks like a museum, and you could eat off the floors, ceilings, walls. That's just her. (Oh, how I envy her sometimes. No, wait, I don't.)
The food thing? Many many dieting and organizational types recommend doing just that. Cook on Sunday, then portion it out. Some to freezer, some to fridge, etc. I had one friend who did that every Sunday, and brought her lunch every day to work with us, all in her Tupperware container. The only time it varies was a) going out with office or b) when she assembled a salad and/or veggie tray the night before.
JMO. Tidy and organized doesn't equal OCD. If so, there may be a lot of professional organizers out there who are going undiagnosed, ahem. And I doubt that.
Plus, you can live messy and be OCD. OCD can focus on certain things, and ignore others.
