Adam was insisting to set up a Kool-Aid stall in his front yard to earn more money. At first, his mother tried to convince him on giving up this idea but the little one made a strong point. When the boy said that it wasn't just about earning but to learn something. His mother was impressed by the little one's efforts and agreed but only on one condition. Krista put her condition in front of Adam, it was that she'll stay there as long as he'll be putting up the stall. Krista's intentions were just to protect her boy what she didn't know was that if something bad has to take place then she will not be able to stop it anyway. Adam instantly agreed and they made a deal.
She never saw this man before which meant he was not from the neighborhood. He was talking to Adam and what took her breath away was the van. There was a van parked right in front of their home. All of sudden, Krista's mind filled with all the negative thoughts and she wasn't completely wrong in worrying about her son.
The man left a letter in the mail box and disappeared. The letter started with, “Adam” And continued, “Remember last week when you were selling Kool-Aid on a hot day? I didn’t have any money but you offered me Kool-Aid anyways. Thanks, man! I was really thirsty. Good things happen to good people like you. Stay cool, dude. Mailman.” Krista was overwhelmed by this man's effort to return the favor that Adam had done to him.
