Bonjour,
Voici des idées en anglais:
- If the teenager is shy well then he or she can write a letter to their parents saying «I'm sorry...».
- The parents and the teenager can come to an agreement so they can all have a better time at home.
- They can all say sorry in the same time since no one wants to be the first one to say it.
- They can try to find some activities that they like to do together instead of doing some that they all don't like.
