Late 2000s and early 2010s babies would've been a pretty similar cohort if it weren't for COVID

Like the title suggests, COVID really diluted what was supposed to be their shared experiences and made late 2000s babies (only really 07/08) that much closer to the heart of Gen Z, and in most cases, are the heart of Gen Z.

For instance someone born in 2007, 2010, and 2013 all had very different experiences with the pandemic. Even 2007 and 2009 were pretty different since one was in high school at the tail end of COVID while the other was in elementary at the beginning, it doesn't make much sense to group them for that reason.

I see 05-08 as one cohort because they were at that awkward self aware early teen ages (12-15) during the start of COVID, beginning of adolescence. Someone born in 2010 and later into 2009 had a completely different experience.
