Mum is over at the house for the first time since the divorce, and Dad actually complimented her on Christmas dinner. John secretly hopes this becomes a tradition again. (As long as she stays off the liquor, she's a lovely person.) Harry seems unusually nervous, and John asks what's wrong.
Harry gulps and says, "Um… I have something to tell you. I was hoping for a better time, but since we're all together…"
Mum asks, "What is it, love?"
"I'm a lesbian."
"Not in this house, you aren't!" Dad shouts.
Harry yells that she can't change who she is, to which Dad responds that she had damn well better try. The conversation degenerates into an argument over which parent is "responsible" for Harry's orientation. Harry shouts back at the both of them. John tries to intervene on Harry's behalf but Mum, Dad, and Harry all bark, "Mind your own business!"
John trudges to his childhood bedroom and flops on the bed morosely. His greatest fear is that he'll never have a decent Christmas.
