QotD: Brush with Celebrity

Last May on holiday, when I was walking around my apartment with my 4 years old son, we met Emperor and Empress. They were, of course, not walking as we were, headed by police cars and motorcycles, with all signals were forced to be blue, driving fast as much as possible. But both were smiling and waving hands to us thru car window, we were just surprised and tried to wave hands.
It was just few seconds long encounter but I was so pleased. Of course, my son had no idea who they are. He was ecxited about "signals, all blue ! no red !! for soooo looong !!"
Yup, boy, it will happen sometime...
