John: Mary has a fever, I’m afraid we won’t be able to come.
Martha: Oh no, it’s such a shame!
John: She’s really sorry that we can’t join you on this special day.
Silvia: Send her my regards, if you need anything, please let me know.
Christine: I’m sure there’ll be plenty of occasions to celebrate, get well!
John: Thank you, Mary sends her love
Mary has a fever, so she and John can't join the celebration.
