Who do you consider your peers?

Now obviously there’s more to peers than just birth years, but in general as a 2007 born, I get along the best with people born in 2002-2010. Although, Me and 2002 borns are 5 years apart but we are both core z so we are peers. Anyone older or younger is just too far from my age imo and there were some differences in the way we grew up. In the future it could extend.
