I learned a lesson several years ago about jumping to conclusions. Ok maybe I've had to learn it a few times. There could have been something else going on or maybe not. Either way it is up to the cruise line to handle it properly.
We were on a cruise years back when I spotted someone that I had worked with maybe 10 years earlier. I said, that looks like so and so, but neither of us were sure. I wanted to go over and say hi, but he was hanging out with this 20 y.o. something girl that was clearly not his wife. I saw him hanging out with her in the bars and dancing with her, and sometimes at dinner and a few times out at the pool. He had his arm around her, even when she was with her friends. He never acknowledged me, so we just kept to ourselves.
When I got back to work, my boss asked how the cruise was. I said, it was great, but I thought I had seen this so and so onboard, but wasn't sure. To which he answered, it was him. His daughter is a dancer on the ship and he went to see her. The wife couldn't leave the business, so she is going in a couple of weeks. I am sure glad I kept my mouth shut!
