I think those 'reasons' despite how emotionally they are portrayed or not on the cards. Basically = i was not wanted.
I dont buy into stories about how sad this was, or that was. It is irrelevant to me. And some stories are horrendous as you have described. If i fuse with all the emotions these cards draw from me, id end up the mad dog woman, overrun with hounds.
I think the comment about breeders breeding blue SBT's, is a great point!
