And no, not the one where you're oblivious to mess, mine is quite the opposite actually. No matter how much I tidy/clean my house, my eye always falls to one little thing out of place, and I find it difficult to take the whole room in as one tidy space. Sometimes I need to take photographs and look at them in order to fully realise that it's tidy 
I grew up in a very messy/cluttered house, so it could be that coming back to bite me. It's very frustrating though as I feel like I can never fully relax as there is always something in my eyeline annoying me!!
Please tell me I'm not alone/how I can get a grip!
