don't care what you think and I'll blame you either way so I'm shutting down.
K: Should I drive 3 hours to pick up a bed for my 26 year old
child when I have to
work? (said with aggression and negativity)
L: No, that doesn't make sense let your adult
child take care of it ( said with a "what are you thinking ?" tone)
K-Nevermind (said angrily with a you're awful tone)
