Live look at the Oklahoma City Thunder fans...
Let's ignore the fact that Kevin Durant is a grown ass man carrying around a team lanyard like a high school/college student that is afraid he's going to lose his keys at every turn unless he feels an unnecessary long strap hanging out of his pocket. The bigger story is obviously that he's ripping a citywide bandaid off and inadvertently dumping salt in the wound he created by doing so. As much as his decision calls for him to be treated as such, he very clearly doesn't have the personality of a villain so I don't think this was intentional by any means. However, that doesn't make it any less inexcusable.
Come on Kev! Haven't you ever been a part of a rough breakup? Don't you understand that a person whose heart you broke is going to look for every single reason to hold on to hope? That they are going to look far too much into little things that you would never even think about? I know it's just a keychain that you've probably had for the last 7-8 years, but to a person that can't get over your departure it's a keychain that represents that you still care. Walking around with a Oklahoma City lanyard is the equivalent of posing for Instagram photos wearing the shirt that your grieving ex-girlfriend bought you. It's bound to lead to a conversation that you don't want to have. It might not be a late night, drunken "I kinda miss you" text, but to them it might as well be. The current state of Thunder fans makes menopausal women look mentally stable. They just lost a top 3 player in the NBA who many assumed wasn't leaving, and people are treating it like it's a foregone conclusion that the other superstar they hold so dearly is no more than a season away from following suit. The last thing they need is a ride on an emotional roller coaster simply because your negligence in failing to visit the Warriors team store has them thinking you're still feeling sentimental.
