Do your friends trust you?

1. Not having time to get married, my friend got divorced, and her ex-husband invites me to his party. I:

I will ask a friend if she minds if I accept the invitation;

Sending a visit, I do not say anything to a friend, so as not to hurt her;

I calmly dress up - I have nothing to justify myself;

I call him and explain that I have and will be more interesting classes.
