Kindness is king! It's so deeply important in life to be kind.
I'm surprised here by your friend saying they would sue everyone involved if she was to receive a blood transfusion. I find it ironic as there could be a situation where she might not survive if it weren't for having received a transfusion — and thus wouldn't be able to sue anyone at all. It seems a little extreme because like you say, those attending to the medical emergency will do all they can to ascertain if the person doesn't want to receive specific procedures due to their beliefs, so if it were to happen it would be reasonable (and kind) to assume it was accidental. But, each to their own!
Those periwinkles look really interesting! How was the soup? Delicious I'm sure!
