Imagine you've run into your favourite actor or idol of all time. What would you ask them?
Does the meeting go well, or do you gape awestruck and drool?
Perhaps, you've been thinking and preparing what you'd say for some time, so when you finally get the chance, you go for it.
Maybe, you've been stalking them. That wasn't very clever. But, now you've got the chance to make history.
Alternatively, there might be someone from history who you get the chance to speak to and ask them some poignant questions.
Celebrities are rarely like the image that they project. They can act badly. All the more so, because they're celebrities.
