Hollie: I'm all shaking
Thea: What happened?
Hollie: I'm so pissed
Hollie: I almost blew at that fat pig
Thea: Helga? What did she do?
Hollie: Nothing more than she normally does.
Hollie: It's been accumulating.
Hollie: She came to dinner and started criticising what I cooked
Hollie: She thinks I don't understand Armenian 
Thea: How dare she come to your house and criticise you like that
Thea: And speaking with the others in Armenian, that's so impolite when she thinks you don't understand.
Hollie's mad at Helga who came to her house and criticised her cooking in Armenian, which she thought Hollie doesn't understand.
