when he gets up to go to the bathroom and he says, in an Australian accent, "I'm going to see a man about a wallaby," and you both laugh, and it goes without saying that it's a reference to Finding Nemo, and it's a wonderful moment of realization that the world of childhood and children's movies have become endemic to the culture of your marriage, your common language, and you're both happy about that, and neither one of you feels like a pathetic loser because you speak in Pixar quotes instead of op-ed quotes, because you're not a loser and you're not alone, and you have your best friend with you, growing up and growing young again with you, laughing at a Finding Nemo pooping quote.
