If a stranger offers you some of their popcorn, it's best to politely decline.
However, if a prince offers you some of his popcorn, it's 100% absolutely A-OK for you to accept.
Whether or not he offered, Prince Harry found himself sharing popcorn with 2-year-old Emily Henson at the Sitting Volleyball Finals tonight during the Invictus Games.
Emily, whose father, Dave, (according to his Twitter profile) is an army veteran, bioengineer and Paralympic athlete, sat opposite the action on her mother's lap, more interested in stadium popcorn than anything else.
Alas, Harry caught Emily stealing his kernels. Instead of giving her a what-for, he made silly faces AND IT WAS ALL WE NEEDED ON THIS SEPTEMBER NIGHT.
Also, I believe Emily was carrying a Royal Canadian Mounted Police Paddington Bear. You take that popcorn, lady. You deserve it.
