You: Why you didn't invited me for your birthday? I was thinking we were best friends.
Luke: Sorry for that. My parents told me that the birthday party was only for family.
You: Why you didn't told me that earlier? I was very mad at you because of that.
Luke: I'm realy sorry. It won't happen again.
You: That's all right. I forgive you.
Luke: Thanks. I really care about our friendship.
