Roomba mops, bidets, and the Secular answer on dust

The shoes-letter banter spirals: Roomba mops in the Costco catalog, bidet experiences at the Nagoya airport in Japan, and "Poseidon's kiss" jokes. Boova (speaker-2) then reads the "Secular" answer, citing the August 2024 issue of Consumer Reports: half of household dust is tracked or carried in from outside, and shoe soles carry viruses — suggesting a doormat compromise. The room mocks the doormat: "she blows right past that doormat."
