cliché or tribe

Are we a cliché? Are we part of a tribe? For example, the other day we were discussing whether we would spend $1000 on a fountain pen if we won the lottery. Most wouldn't, but a couple said they most definitely would. Because the $1000 fountain pen was part of their identity as a subculture. That and Moleskines, of course.

We decided that we can be both. We can be a cliche to outsiders, and part of a tribe to the insiders.
