I am so so sorry about Shaianne. It would have been such a shocking experience for you. But you were with her & that would have eased her distress.
That was such a lovely & wise remark your Mom made about how Shaianne would go to comfort those who died, with gentle licks on their hands. And your Dad was wonderful, too, to make sure that Shaianne was laid to rest with love & care.
I hope you can feel the hugs I'm sending you.
