On our Bermuda cruise a couple years ago, we were waiting for them to open the doors to the dining room for dinner.
I was standing next to my husband the whole time, then I stepped away to look at something. He thought I was still next to him and he put his arm around some guys waist.
I saw the whole thing and I was dieing laughing.
My husband was mortified and the guy was in shock. My husb blurted out he thought I was next to him... and everyone had a good laugh!
