The star player has lots of friends, He stands in the center of the field surrounded by all of the other players, and everyone is cheering for him when he makes a goal.
He has never known what it is like to be on the sidelines.
The player on the sidelines, watches from afar. When the player on the sidelines works hard to please everyone, no one cheers for him.
Now the player on the sidelines does not feel that the star player has an obligation to let him join in the main game.
He just wishes that the star player knew what it felt like... to be on the sidelines.
