I fear I am both woefully behind on the news as of late; had I heard sooner of your sister-in-law's reappearance, I would have written to make sure you were alright. I also admit that perhaps, I am not always one to give proper advice, but I shall indeed do my best for you.

I believe your heart is in the right place and that you were being incredibly considerate of a possible relationship between the children and their aunt. Vampirism, as far as I am aware, does not always completely change the person so much as their methods of survival. Clearly she has been handling this for a while and should she want to have any sort of contact with your niece and nephew she will know what it takes to see that through- and if she is capable of doing so.

In reaching out to her you have left the decision up to her and hopefully she will consider carefully. Should she accept and wish to see the children and you still feel uncomfortable about the meeting, I shall make it my priority to be available as an extra measure of caution.

I do hope some of this puts your mind at ease.
