There’s a throwaway “tell them their sisters are prostitutes” from Watney that – since we were driving the kids on a road trip, and listening to the audiobook – provided a teachable moment about misogyny.
When life gives you gratuitously sexist lemons, etc. etc.
Correction: The exact line is “Also, please tell them that each and everyone of their mothers is a prostitute. —Watney. P.S.: Their sisters, too.”
