Ah, I have never met him, sadly. (the autograph was given to me by a friend)
(and i got Benedict and Martin's autographs with the Big Chief Studios figures)
Yes, if I ever met him (I can't see that happening, unfortunately... No chance he comes anywhere near me in France, and as for the SherlockED conventions, I couldn't make it to the first one in London --the timing was bad-- and I was so happy when I saw the dates for the next one --I could take days off work this time-- and then I realised it was in Birmingham. Too far, too expensive...), asking for his autograph wouldn't be the first thing which would cross my mind. (although, of course, if he proposed himself to sign something for me or to take a picture, i would not say no, obviously!
I think it would be lovely just to chat with him (even if it were just a minute) but I would be far too shy, wouldn't know what to say, would be afraid to make him waste his time...
I mean, there are only a couple of "celebrities" (singers, authors, actors...) who I really admire and adore (mark is one of them). I have only had the chance to meet one so far: Graham Coxon (Blur's guitarist. I'm a huge fan of his solo career). I have been lucky to win a ticket for a very private Blur's gig in 2015. I spent the whole concert standing just in front of Graham ( next to the foot of his microphone) and was already in Heaven. My little boy (who happens to love Blur) had drawn something for Graham's birthday and I had written a letter in which I explained how much his music meant to me. Just in case. At the end of the concert, I found the courage to tap him on the shoulder, but when he turned around and came closer to me, I was pratically speechless and felt like I didn't know how to speak English anymore.
I felt so embarrassed! (I managed to give him the letter and the drawing though)
I think the same thing would happen if I ever met Mark. And then I would hate myself for having been unable to string two words together!
