Contact letters

I've just finished, what I find to be the hardest job to do each year - Little Prince's letterbox contact letters. I know it is extremely important to write and send these letters, as it will keep a (probably tenuous) connection alive between Little Prince and his birth family, but I still find it hard to write. I'm pretty good at self analysis, but I'm not sure why I find it so difficult to write these letters. But whatever my problem with them is, they are now finally written and waiting to be sent off as soon as I hear back from the social services dept with confirmation of the birth family details.
