I do not expect nor ask for forgiveness but I wanted to apologise for my actions last week. I had been afflicted by the amnesia that was going around and had lost some rather important memories when I encountered you in the library. I did not remember who you were at the time nor that we had met previously. Not that that excuses my behaviour in the least. I hope that you are all right and that you were not injured too badly. I am terribly sorry.
