I think the connections of thread between hearts can be knit and held secure, or knotted so tight you gave to rob the string of its fibers, ripping it apart, to part the string, and even that doesn't undo the knot, just leaves it torn to one side (me or you when one of us dies). but sometimes string is tied so loosely it can be pulled apart by the wind or any passing vibration in the sand.
I think you have cared more deeply than anyone else about living or their own lives and they have shamed you for it or thought of you as insane, for fighting so hard for A Dog's life, when even your wife (a dog) has accepted without question this is just what a dog's life is. whenever your wife sees a dog fighting its leash or even standing defiantly against its owner its tied to, your wife thinks he is "a (one of these)" more than any human master pet-owner and understands that part of being a pet is that your life is dictated by your handler and you either obey or get beaten to death, and if this woman froze her dead dog in the wind bc her coffee took too long, she would call animal control to dispose of the garbage and no one would look twice.
your wife only narrowly escaped this fate of someone owning his life or death and dying unnoticed except as corpse garbage by becoming a dog that became the master of yuui's menagerie.
but even though your wife is a little bewildered that you don't understand even this much about (animal) ownership (CAN YOU "REALLY" CALL IT SLAVERY?) I think you see in your heart what happened to me in that dog. and that's why you fought so hard. and refused to accept no one could do anything.
but the enemy is the sand...
I love you. happy every day together forever. til death do us part.
