Very messy!!
I used to be much tidier. That was before the internet lol.Been known to cry over mess.
Like other posters mentioned my "tidy" is not the same as other people's "tidy". My order might look illogical to other people, but to me it makes perfect sense why i've put something there and not somewhere else.
I tend to let mess build up to the tolerance threshold, and when it's virtually impossible to circulate around the house I start tidying up.
And when I do start tidying up I just can't throw everything into a drawer. I need to neatly classify everything and put it where it makes the most sense for it to be.
I specially have problems with clothes and paperwork.
I think it might be something to do with the photographic memory thing, but I need to see my clothes to remember where they are whether they're clean or not. So I've got a bookcase to put the clothes that cannot be hanging, like t-shirts and jumpers, and i've got them all on piles for winter, summer, t-shirts, vests, cardigans, etc
Paperwork, I need to have it all in associated folders, so things tend to lie around here and there on tables and desks until I get round to putting them away where I will find them next time I go looking for them. If I need anything before it has been duly catalogued and archived I just have to rely on my photographic memory -only that sometimes I mix my albums
