As this masked lapwing was going to St. Ives, he met a man with seven wives. Every wife had seven sacks, every sack had seven cats, every cat had seven kitts. Kitts, cats, sacks, wives, he asked how such a familial structure was economically sustainable.
One of the wives responded that they were cat breeders heading to St. Ives for the big kitty conference where they would sell their knowledge to other cat fanciers and find homes for the kittens. They could then use the money to help support their husband when he went back to school to train to become a nurse.
Thus was the lapwing educated about heteronormative assumptions.
