Does my husband sit on the train and worry that the crushing dullness of Collateralised Loan Obligations might be leaking into Lanny? I doubt it. Does he feel disgusted and ashamed that his phone, which Lanny uses to look up videos of blue whales, is the same phone on which he watches porn, sadly whacking away at himself in the bathroom while I pretend to be dreaming of murder plots? No, he doesn’t. Such burdens are always hers.
