The rules of riding a tandem:
1) The person at the back must cycle as much as the rider at the front. Just because you are out of sight, does not mean that you can slack off.
2) Work out who has the worst body odour and make them the rider at the back.
3) If the person at the front is silly enough to steer the cycle into danger, the person at the back is perfectly entitled to use them as an air bag for protection.
4) It is cruel to apply the brakes when travelling up hill without letting the other rider know that you are doing this.
