You are a 1st grader with $5000, and you have time to wait. What do you do?

You've got $5000. My friend from work has just given it to me. He owes me $5000 and he has left this in my hands to give to his little brother, who is in class right now. He had to leave before he could give it to his brother and asked me to do it for him. I'm a substitute teacher, it's finals in high school and the students are doing the AP final right now, so I'm not super busy. I will get the little brother after school, and I promise to take good care of what he is owed. <br><br>I sit at the desk in the class and unfold the wad of $100 bills, and I start to play with them. I keep them in stacks of ten as much as I can, and spread them out on the desk. I look up to see around ten teenage heads turn to look at the desk. "Don't worry, none of this is mine" I say, and scrunch my face up at the students. They all look at me oddly, and turn back to finals. <br><br>What is $5000 to a 6 year old? I imagine he will buy video games or candy or something. Too bad he doesn't have the money now, I think briefly. I guess I have almost 2 hours to kill before he is out of class. <br><br>I count the stacks that are done. There are around 50 stacks. I multiply by 10, and I have 500 $100 bills. I pull one of the stacks and count it out $100 by $100. <br><br>I have a thought. If I made 500 piles of ten $100 bills each, and I took one $100 from each pile, then I would have 50 piles of nine $100 bills, and one pile of 500 $100 bills. I could get that pile and leave the 50 piles of nine $100 bills that way this little boy has 50 piles of $900. I count out the $100 bills, and then I divide them into 50 piles. I then take one $100 bill out of each of 50 piles. I give all the $100 bills back to their original stack and put the money back together. <br><br>$5000 - $5000 is nothing, I think to my self. Then I put the $5000 that I was going to take in my pocket, and proceed to grade papework and watch the class. <br><br>The students finish the test and they file out. I go to the kindergarten classroom on the other side of campus and find the boy I am looking for. There are about 30 kids in the classroom, but I recognize him from the description my friend gave me. I walk up to him, and he asks me if he is in trouble. I tell him he most certainly is not, but his brother owes him some money. He smiles as I hand him the $5000. "Did my brother give you a hard time about giving me this?" he asks, and I smile back to him and say "No". <br><br>He thanks me, and puts the $5000 in his backpack. I ask him what he is going to do with all that money, and he smiles again at me. "I don't know" he says. "I have enough that I can do anything I want." (edit: at least 1 person was confused here, to clarify he says this right after I hand him the $5000)<br><br>I smile back at him, and say "Good boy."<br><br>And that is that.
