Question
Work in groups. Discuss these questions.
Answer
This means it is better to do things (e.g. organise a day out with someone) than to say you will do things and not do them.
This means it is good to make promises because it shows you want to try to do good things or make people happy (e.g. it is better to promise to love someone, only for a relationship to fail later, than it is to be the sort of person who never commits to a relationship).
