Your sentence's are rather choppy and short. I am having trouble picturing what these people look like, where they are, so I would suggest some extra details in there. I was confused with the whole Sir and saluting things. I couldn;t tell if it was a giant joke or serious, a bit of clarity would be nice. I would also recommend taking it slower because it seems like they are already dating and how old are these guys? Because in your summary I was really confused that they were being sent to elementary school. Were they home schooled or something? I think you to clear up a few points and your story would be much improved. Good luck and may your pen be ever in your favor.
