Severus, the only interaction I have had with you in years was through Dumbledore, concerning the Wolfsbane potion. Time in this place is neither exact or specific and bears very little relevance to each of us in turn.

Whatever magic is at work here pulls each of us out of distinct and separate points within our timelines.

I know we have never been more than professional, but I have not found myself to be on particularly unpleasant terms with you since the childish days of our youth. And if that is the time that you are referring to, then I would say you are a bit over dramatic.
