I have to share this as a big sports fan and a long time suffering Cleveland sports fan. In 2016 I was in WDW and staying at the VGF when the Cleveland Cavaliers were playing the Golden State Warriors for the NBA championship. The Cavs were down 3-1 in the series. While walking from the resort to the mono-rail I saw a GS fan wearing his team proudly (as he should), and I was wearing my Cavs shirt proudly. As I walked past him I tried to be polite and told him, "should be a good game tonight." His response was a rather nasty, "Yea Right, not a chance pal."
Well most know how that series turned out. For game 7 I was not going to miss it for the world. I ended up watching the game at the Grand Floridian in Mizner's Lounge. Who else was there? You got it, the guy I saw a few days earlier. When the buzzer sounded, the Cavs won it, I turned to my nephew and I swear I told him, "Did we win." "What do we do were Cleveland fans." LOL It took a few seconds before it sank in and we celebrated with the loudest shout you could ever hear, and I'll admit some tears as well. The Warriors fan, well he came over and offered to buy us a round of drinks on him. I don't drink so it was a Diet Coke for me.
Congrats to the OP, your Chiefs won it!
