If you could travel back in time to meet a person (only one) from history, what person would you like to meet? What would you say to him/her?

<em>For me, I would like to meet my late Grandfather. I didn't have an opportunity to stand by him at the moment he passed away. I would say to him that I will make him proud :)</em>

How about you? Do you want to meet a famous scientist like Albert Einstein, Isaac Newton,a famous King, a president, a general like Napoleon, etc... or just like me, a family member, who passed away...? Give me yout thought!
