Matt got confident after knowing that it was so easy to blackmail Kate, "Heh, no wonder Erin is so happy whenever she blackmails Kate. Turns out this woman, who acts arrogant and snobby, is actually a big coward who would cower in fear just because of a small threat."
Matt didn't understand why he often got intimidated by Kate.
True, she was very cold to him many times, especially when Matt asked for more money to buy more games for his consoles.
True, she often yelled at him, telling him to do the dishes or at least clean up his couch.
True, she often nagged him to get a job when he was in full focus when playing online games.
Kate was a dominating wife that wouldn't stop nagging and nagging just because he was unemployed.
"But why am I scared of her? What makes that ugly nerd freak from high school any different just because she gets her own money now?"
Matt found himself ridiculous.
