Well, seeing as i fell asleep the moment i got back from London yesterday, and just so I can keep a digital log of my Brent-Spiner-stalking, I reckoned i'd make a note here. ;D Yay me.
So. Mr Spiner.
The man was one of the nicest people i have ever had the pleasure of meeting.
I managed to interact with him twice, although the first time was just a fluke; I was standing in the queue, waiting patiently for him to sign the photo of Data i had selected, when he looked directly at me, held out a photo he had started to write on and asked me to get a new one from the lady selling autographs for him. I guess he'd made a mistake, or something? XD
