Never again believe what you read.
Never again fly on the most overbooked air travel day of the year.
Never again go via this airline through this airport.
Never again be in a hurry to get home when fog socks in your destination.
Never again leave your dog at home with a dogsitter who misunderstands/misreads/forgets when you are returning.
Never again get the smell of fear, anxiety, panic and dog poop out of the rugs.
Never again use sudsing detergent in your new front-loader.
