An Octopus friend! This weak octopus approached this woman and she healed it at her home

I saved this video clip of this unique relationship with an octopus and the woman who helped brought it home to heal and returned it to the ocean.
Then visited her when she returned and it joined her friends !
I have met octopus while diving but they were never friendly.
Then I saw the movie "My Octopus Teacher", which I recommend to everyone!
Apparently this is actually not so uncommon.
