A short story, but i remember in 1nd - 5th grade at my elementary school here is the list from first to last for being cool at school 1. Lego and Pokemon cards
2. Having lunchables and good stuff while i had that whole wheat bread pb and stuff
and tuna that i don't even like and stuff (unless it's a field trip)
3. Yu-gi-oh cards
4. Slime
5. Nothing that much but showing your new phone and where you went over the weekend, while i stayed at home doing mostly nothing productive
