One last look, for the moment, at the word slave, with definitions found through Google.
1. slave – a person who is owned by someone
2. slave – someone entirely dominated by some influence or person;
“A person who is held in bondage to another; one who is wholly subject to the will of another; one who is held as a chattel; one who has no freedom of action, but whose person and services are wholly under the control of another.
“One who has lost the power of resistance; one who surrenders himself to any power whatever; as, a slave to passion, to lust, to strong drink, to ambition.”
As you have seen before in a post by Amy, she has some real problems with the word “slave”, and isn’t comfortable with the very harsh reality of slavery, as contrasted with the kind of relationship that we have.
I’ll leave it to you to decide your own feelings about the word “slave.” There is enough flexibility in the various definitions for me.
I see a state of mind.
Namely, that Amy has lost the power of resistance, has surrendered herself, and is entirely dominated and owned.
Works for me.
