Well, back in the 1950's,we lived in a mansion block in London.
I arrived home from work (at 2.am) and thought I would surprise the wife.
I stripped off in the lift,and as our flat was directly opposite I stepped our (in the buff) and rang the door bell.I was quite excited (if you see what I mean) BUT the door was opened by my Father who had come to stay (with my Mother) unexpectedly. He hustled me into a bedroom and I dressed (quickly).Luck it wasn't my Mother or I would never had heard the end of it!(she's a very prudish) unlike my Father who kept bursting into laughter for a couple of days,much to my Mother's annoyance and confusion!
So just be careful.
