Hmm, she's interested in the design, aesthetic and shape of a space in the same way, but is much more concerned with 'clean and tidy'. She can't really bear untidiness, though you'd never know because she isn't 'in your face' about it. She cleans up and organises things to de-stress sometimes, and might rearrange a room I think to give that sense of 'a fresh start' (which I do too).
When I tidy up properly, I enjoy it for the sense of accomplishment and perfection, but she really enjoys it a whole lot more. Sometimes she's like a tidy elf; I'll leave the room briefly, only to return and notice that things look different, but she somehow hasn't moved, or I'll realise later that my undershirts have been folded... She actually enjoys washing up after dinner more than cooking, which is ideal for me because I like cooking but washing up is a chore (except polishing and oiling the wok... I like that for some reason).
What type is your SO, Asa?
