A while back my wife and I were on a cruise, and decided to film a video of our room/balcony etc to send to the family so they could see what we were up to and how excited we were to be there.
I went around the room filming the view, the bed, bathroom, etc. I showed it to my wife before sending to my family to make sure I didn't say anything stupid or something.
Halfway through, she says "Babe, you're naked. Many times."
In fact I was naked, while filming, but didn't realize how many reflective surfaces (including full on mirrors) there are in a cruise suite haha.
Needless to say I re-filmed before sending, this time with clothes on.
