Just think of the barking and howling going on when they are left in the cabin. How about the ankle snappers. One has to relieve themselves and they do it on someone's fine evening gown. A plate of food is on a table and the person turns their back to look behind them and the food is gone. Throwing a frisbee around and it goes over the rail but starts back as they do. The dog runs for the frisbee and ooppss. Not to mention the odor of a wet dog. That is why my ex didn't cruise much because she has three dogs and had problems finding keepers for them.
Good people sleep peaceably in their beds at night only because rough men stand ready to do violence on their behalf.
Courage and perserverance have a magical talisman; before which difficulties disappear and obstacles vanish into the air.
Pick your company wisely! Hang around people who are going to help you become all God created you to be.
