With: together. Alone: just the man and the nun. Stands with: if she stands within arm’s reach of the man, she commits an offense entailing confession. Talks with: if she stands talking within arm’s reach of the man, she commits an offense entailing confession. If she stands or talks outside of arm’s reach, she commits an offense of wrong conduct. If she stands or talks with a male spirit, a male ghost, a <i lang='pi' translate='no'>paṇḍaka</i>, or a male animal in human form, she commits an offense of wrong conduct.

Non-offenses There is no offense:

if she has a companion who understands; if she is not seeking privacy; if she stands or talks thinking of something else; if she is insane; if she is the first offender. The third training rule is finished.

Origin story At one time the Buddha was staying at Sāvatthī in the Jeta Grove, Anāthapiṇḍika’s Monastery. At that time the nun Thullanandā stood and talked alone with men on streets, in cul-de-sacs, and at intersections, and she whispered in their ears and dismissed her companion nun.
