What to expect in a relationship

A new listener’s reading for this podcast episode:

‘What to expect in this relationship?’

And Yi’s answer –

Hexagram 41, Decreasing, changing to 26, Great Tending (or Taming or Nurturing…), with changing line 3:

‘Three people walking,
Hence decreased by one person.
One person walking,
Hence gains a friend.’

Hexagram 41, line 3

Who are the people walking, and what could this be about?

(If you’d like some more listening/reading, here’s an earlier episode that also started with Hexagram 41, and here’s a post about how mountain works as outer trigram.)
