My wife is always getting changed, walking round nude, standing in front of windows and patio doors at home. Its not for the attention she just either doesn't realise or doesn't care (a bit of both I think) its like she doesn't even realise its a window!! The neighbours must have seen her dozens of times as they only have to look out of their windows at the back of the house.
She also goes out to get clothes off the line without dressing, again not for the thrill, she just doesn't care and neither do I lol
