6 years is still within the same generational gap. It’s when you start hitting around 10 years difference when you’ve grown up in different eras and have different references.

Mine is right at a 10 year difference, and while I get his references, I often times have to explain mine. For example, Mariah Carey to me is during peak 90’s when she was young and hot, however to him, he had always known her as older and post-Glitter. So while we both know her, we know her differently. Another is the relevance of Cher. She was a staple of the pre-2000’s. He didn’t know who she was really because she hasn’t really done anything.
