when a child tells you, "you look like Santa" while you are going about your shopping, and you say "Oh, yes, Santa" and the child then says " you can't be Santa, Santa brings presents" and you say again "oh, yes, that's right, I am just an imposter" And finally waiting at the check out you hear the child say to its mother, " there's Santa's brother" You know you have had a really unique encounter just by doing your same old same shopping.
