1) Nancy receive a email and an invitation by Kelly, but she can't go with her because she already has a meet with John to visit Nepal next summer. He and she leave on the 1st of July and they won't be back before the end of the month.
Nancy asks Kelly if they can arrange a weekend together in August.
2) It is an email because there are e-mail addresses and it is on computer.
voilà ! pour la 3) je sais pas trop, désolé ^^'
