It's all good.

Speak as Trisha
Trisha: What's wrong?
Stacey: I'm not going to be able to attend your Christmas party this year.
Trisha: Why not?
Stacey: My family has decided to take a family trip this year, so I have to go with them. We leave on the same day as your party.
Trisha: That's too bad.
Stacey: Are you mad?
Trisha: Of course not. It's all good. I completely understand – family first.
Stacey: Thanks for understanding. You know I would be there if I could.
