I managed to meet up with R2-D2 and C-3P0 when I was last at the weekend in 2005. It was great to chat away with them, and of course I learnt some tips about how to keep my brass shiny at home!
I also met Darth Vader - whilst he's not really my 'friend', per se, I couldn't really call him my enemy...well, not to his face anyway. Can you see how nervous I was standing next to him? That smile is forced, let me tell ya!
