It's all changed!!!!!

It's really strange but I don't seem to recognise ANYTHING here in NY. It's as if I've never been here before! I can remember the objective geohraphy - where 5th Ave is, where the Village is etc....., but I have no sensation of memory whatsoever that I was here. It is very strange indeed. Here's a photo of me outside the flat I lived in on 16th Street. Maybe the city has changed so much, or maybe my brain is too addled!
