Based on your original post, you were cruising the Med, MSC caters a lot to Europeans, I would think even more so in the Med so could it be a chance that you maybe just didn't fit in? Maybe the expected comfort zones weren't there?
Again based on your other post. You requested information about doing things on your own, which would indicate you are an adventurer, adventurers are usually adaptable, was the ships service so despicable that it overpowered your ability to adapt???
