Mark and Carol are like most brothers and sisters - sometimes they agree and sometimes they don't. They agree that going to stay with their grandmother by the sea is great fun and can't wait to get there, but their fights with each other have been getting worse and worse and threatening to spoil the fun. Besides, Grandmother won't put up with it.
