That schedule took
shape because men, whose wives tended to domestic responsibilities during the
day, literally had nothing to concern themselves with
other than bringing home a paycheck.
The
shape of the distribution was also much flatter, such that it took over two months for three quarters to be adopted, appreciably longer
than the
other breed labels (e.g., three quarters of all adopted adult dogs labeled «Chihuahua» had departed the shelter within eleven
days).
