Forgot to Close the Curtains One Night

I was working late one night and just couldn't be bothered with closing the curtains. So I left them open while I had a shower, not thinking much of it. Next thing I know, my partner comes home and asks if someone could've seen me undressed through the window. Turns out a neighbor down the street saw me. I panicked, lied about it for days until he found out. Silly mistake, right?
