Friendly and passionate about things - but carefully camouflaged by an outer suit of cool detachment. "What, the ceiling of the Sistine Chapel? Yeahhhh s'all right..." Dudes! - looking keen is so 'last millennium', etc...

If you're never in the box, you never have to think outside it.

Enjoy: tiny wars of attrition with authority, peach squash, seeing new stuff on a daily basis, dogs who tilt their heads.

Don't enjoy: shouty advert slogans - they cheapen life.
