I think the author is trying to show how kids' evenings look during the summer rather than it be where he grew up or where he saw in his life. I think he is also trying to show kids imaginations and how they see all these things they could want, and they imagine what could make them better. “‘Or maybe even like . . . like some pastrami or something like that.' Jamal, inspired by the beef and broccoli sandwich, revises his original idea. 'And you just stack it up. Like a fistful of it, and instead of putting it on a hero or on slices, or even on a regular roll, you put it on a challah roll’” (Reynolds). This shows how they have that imagination that keeps them thinking.
Another thing, I also think this could show how they don't have much money and how they could be struggling to get through and that's why they didn't get those big sandwiches that they were imagining. “And then Flaco returns from the kitchen with four bowls, a box of cereal, and a half gallon of milk. ‘Don’t worry,’ he says. ‘I got sugar’” (Reynolds). This shows how, after all the talk about sandwiches and what they could have, and they wanted, they ended up with a series which could reference their financial situation.
When it comes to me, I can relate to the fact of fantasizing about what food I would like but not going out and not getting it. This also relates to how me and my friends make fun of each other and how we would talk when we are doing so. This also shows how, at the end of the day, we end up eating simple food because it's easier to do so rather than get something good to eat.
When you said, "I also think this could show how they don't have much money and how they could be struggling to get through and that's why they didn't get those big sandwiches that they were imagining" it was very insightful. I didn't think about how they could have been dreaming about food, all to end up with cereal, because they could not afford it. I can relate to having big dreams but not a way to pursue them, so I settle. Do you think it's ok to settle? Should we be finding ways to reach our goals?
