I don't see the problem with this - it seems to me like someone who is thoroughly enjoying life.

If you're frequently over-the-moon with joy at your meals, your movies, the animals you run across, your job, or whatever, it seems like a fundamentally good state to be in.

I'd say we need more context to say anything about this friend. I have friends who are very 'hyperbolic', but seem so honest. It's like they experience things as a child, or for the first time.

I also have friends who do this, where it seems to be a mask they put on. These friends often have rather unpleasant pasts.

It's a bit like the manic pixie dream girl, to use a fascinating stereotype. I have often tried to delve deep, and it's sometimes really hard to discern the 'broken' kind from the truly 'child-like' type.

Broad strokes, I know, and please forgive me. The only point I want to make is that context is everything in this case.

I agree with you, it is a good state to be in. The issue I take is my overall hyperbole in my own speech. I want to enjoy life, and I do. I want to be more thoughtful and considerate of the things passing through my life rather than writing them off as the highest high or the lowest low in whatever category they fall in.

Agreed. The most overuse arises from the meaning of "ever", where it can mean t=[0, ∞], t=[-∞, 0], and t=[-∞, ∞] (0 being the present).

If everything is special, nothing is.
