Hat.
Boredom on that level would be torture. Ruin all relationships and all hobbies.
As a hat i get to see the world, provided my wearer travels and I’m not just stuck in a shelf for years.
Also afaik a hat is immortal. Silently observing the world until eventually scrapped and burned in a recycling yard.
Depends on the artist and venue. I very rarely pay 50€ or more. 20-35 is my usual price range.
