That's the whole problem with Karen, really. She never seems to have learned to put on a 'game face'. When she's into something, she's really into something. But when she's not into something, she doesn't even pretend to try and engage with the other person and bumbles her way along in the most agonizing way possible. It's why I really don't like her. She never seems to care if she's hurting the content of the other person she's interacting with, she just disengages and lets them handle everything. I could forgive it in her early days, but it's something she has never made a significant effort to overcome.
