A cruise without me
In all honesty, maybe it is better that your friends went on a cruise without you. We have seen what cruise ships look like lately and we are not impressed. There are a lot of strange characters on a cruise boat and things can get really messy at the buffet lineup.
Maybe if you are friends with the type of people that go on cruises often, it’s best to just avoid them and find a different group that enjoys other things. Preferably anything but going on cruise boats, seriously, they are not a pretty sight or a collection of the best people from society.
