Out in door-to-door, with a pretty sister my age, late teens. The usual plethora of not-at-homes. Typical morning, in "the work."
Two dogs show up and start following us, and we can't ditch them. When some householder finally opens the door, the dogs -- so it happens, male AND female -- begin copulating. The sister began laughing uncontrollably and ran off.
That's all I remember, four of "us" at the door, and then "we" became three . . .
