As a young baseball fan, there's absolutely nothing more important than catching a live ball at the baseball park. Well, unless the park serves ice cream at the seventh-inning stretch anyway.
But still: baseballs careening around the park and into your glove = very important. When you don't catch one that comes near you, it's a brutal blow to your self-esteem and happiness.
And, if you're a youthful Giants fan, perhaps you'll start pouting like the kid in this video, who just missed a foul ball from Brandon Belt (who, yes, had a very good night as he powered the Giants to a win).
As the fellas note on the broadcast, this kid is Will Clark 2.0 with that stoneface, and even getting an extra ball from someone in the park isn't going to cheer him up.
Of course, that may be because, as 'Duk at Big League Stew notes, not only did he not receive the "it's a kid hook him up with the ball" action, but he also had the lady shove it in his face by raising the ball in the air and screaming gleefully.
