In the most part kids born in the 90s and kids born in the 00s are the same or on the cusp of the same generation. People aren't having kids at 16-20 that much anymore. (Don't let MTV fool you). So yes there is a age difference between them but of course there is.
I really don't understand the point in your opening thread other than to say "I am a mature person born in the 90s"
No offence intended.
