So the old man didn't believe the kid, and decided to stalk him maybe he finds out his dear grandson...He kept walking beyond the child till he found himself at a dark and dirty street, he smelt something's going wrong!
Then, he saw that boy delivring a guy cash! So he doubted that that guy is a gangster who's using teens in their crimes and robberies, And maybe his grandson is also used them? ,, So he decided bravely to talk that man. "U're using those poor kids for ur crimes! ah?!" the old man roughly said
"Oh man, come on, what do u see! This kid is my nephew and he brought me my money from his dad! " with a yellow smile in his face, the guy answered
"Really? Oh excuse me! I can't keep quiet because I've been blinde since my grandson disappeard! U know, he's the only hope of my life "
