Did the Grim reaper test him? Like he didn’t curse him with immortality right away he told him he’d save a life.
If he had agreed instead of firmly rejected would he have just lived to his old age or would he have aged slower?
Instead he got a knife to the stomach (life time of pain) and the knowledge that he could only die if it was removed (wonder if it’s true since Grim wanted him alive to save ‘that’ life [do t know if it’s hers yet but I suspect so])
It’s kind of like that story with the girl with the green ribbon around her neck and she met a boy when she was on the swing asking why she always wore it. And unlike most boys he left it alone when she told him to Every time he asked and when she was on her death bed she brought up the green ribbon and asked him to remove it, (they’d been married for their whole lives, nice on not pulling her ‘pigtails’) curious he did and to his horror and possibly her relief her head fell off, the ribbon was the only thing that kept it attached
I think it had so many lessons, leave someone be if they don’t want to tell you something, respect it enough and they may tell you themselves. If you don’t it may have consequences that are horrible
Honestly a story like that rarely has a good ending, can’t say ‘happy’ since she died, bit it was Her choice at the end, not a child’s curiosity, animosity (be it child or husband, surely that’d had arguments over the years and if her husband had truly wanted to hurt her (hit, verbally abuse, etc.) he would have first removed her ribbon and like most victims she would have paid the consequence, her life, while he only a shock and being pissed off about having to hide the body… wonder if the author intended it as a warning for bullies too?
