Why does it seem to me like 4th graders are way less mature than people who were 4th graders just a few years ago?
My brother is now in the 4th grade and he acts like a second grader. He doesn't know what sex is, and he I very childish. My brother and I are almost identical and we share most genes. When I was in 4th grade, I was very mature, which seems to be the complete opposite in his case. My brothers friends are also immature.
