I enjoyed your story, @churchboy. You have a gift for storytelling. A lot transpires in this sweet little tale. I wish it was not such a universal concept that kids are bullied, left out, or belittled for their ability to play sports, their appearance, and other things that really don't represent the whole person. But it really is common, everywhere.
These were some of my favorite lines because they capture that phenomenon so well:
Kalu was always the last to be chosen to play for any team, especially when he did not own the ball, and that meant that if the number of players were odd, Kalu would not play. There were two reasons for this: Kalu was overweight from all the pastries his mother gave him for lunch, and he was a bad player. As a result, Kalu was popular during lunch breaks but unpopular during football matches.
One thing I was wondering about is whether you meant "left cheek" in one instance, where you have "right cheek" twice.
Nice work. And great feature, @adsactly.
