Good morning, Yuriya.
(1) Where did she get off calling me untrustworthy?
(a) Something like:
How dare she call me that!
What a nerve of her to call me that!
Who does she think she is to call me that!
(2) By the way, those two little words can mean many things in
different contexts. I would be VERY careful before using them.
Have a nice day!
