A few days ago I went on vacation with my family to Universal Studios Orlando. On our first day there, I wore a shirt that looks like Goku's from Dragonball Z (plain orange with King Kai's symbol/ Turtle Sage symbol). As my sister and I were in line for MIB: Alien Attack, an attendant casually walked up to me and asked politely, "So, what was your score on your last ride?", to which I replied, "Around 200,000." Suddenly his voice got loud and he said, "Really? Because IT'S OVER 9000!!!!!" I was completely astonished that someone I had never met could be so awesome and make my day so easily and all I could do was punch the air with a big stupid grin on my face.
And thus, someone who I will likely never meet again in my life proved to me that you don't have to know someone personally to show them a kindness or make their day.
