Celebrities often experience a very one-sided connection with their fans, and even if they put on a good show with the "I love each and every one of you," Instagram captions, the truth is usually a bit different. Musicians or artists who make their living off of baring their soul and sharing personal experiences can often make their fans feel like they're a close friend, but when fans actually get to talk to them in real life that fantasy can be completely shattered.
Of course, everyone is allowed to have a bad day every once in awhile. Going out of your way to be hostile or rude to fans who are incredibly excited to meet you, though, is never a good look no matter how horrible your day at the airport is. If you have a celebrity you deeply admire, it's probably best to never be in the same room as them in reality. Let the dream live!
