LOL . . haven't done one of these in awhile.
it depends on the actor/role model.
If it was Simon, I'd think I'd just invite him in for a cup of tea and offer to let him use my computer to find directions to where he is going.
I'd most likely do the same with anyone else that I haven't met or spoken to before, but there is a bigger chance of me suppressing a ton of fangirly squee in the process and possibly giggling/grinning like a deranged person or saying something silly while talking to them out of nervousness.
I've seen Simon in person so many times by now, that it's just like talking to an old friend you haven't seen in awhile.
OK - next question . . .( and I only ask this because I'm about to go on a strict diet and exercise regime. *sigh*)
So you are starving . . and you can go anywhere and have anything to eat - money and location no object. Where do you go to get something to eat and what is it?
