Or are you pretty careless?
It really depends on the object, and certainly not necessarily because of the monetary value.
A scratch on my car? I don't give a crap; life is short enough to take this stuff personally. Still, I don't drive it recklessly and I don't do anything to willfully damage it.
My phone? I use it every day, I have a case for it. If it breaks, it breaks. I do what is reasonable to prevent it without being obsessed by it. Again, life is short and I'll not make an object determine my mood whenever possible.
Other objects I truly don't care and I might do actions that destroy them. While other objects, I do take care of them (for example I have some books in a plastic bag to protect them; I don't care about their monetary value, some of them are worth quite a bit, some of them are worth ten bucks).
Nothing winds me up the most is when people don’t care about their belongings and when they don’t have respect for other peoples stuff.
Look, we have another thread here by and about a father who lost his daughter. Another user replied that he lost all his children in a car accident. We had a 300+ fatalities bombing the other way, and so on. That stuff should wind you up
a bit. What people do with their own objects they paid for through their work? I don't see the problem. I work my butt off like many other people, and part of it is to buy objects I want and not necessarily need, to do with them whatever I want. If I want to buy an iPhone XS to just throw it in a volcano that's my business.
I drive on the motorway here in the UK a lot for my work commute, and I see people SMOKING in a brand new, 4 week old, 2019 plate car? What the... why would you?
Simple: Because that's how they want enjoy their new purchase. Considering that the UK has a taxpayer funded healthcare system I'd be more concerned of them smoking at all rather than where they're smoking as that would really apply to you. If they smoke in the car, in a cabinet, or in their brand new yacht doesn't make a difference to you.
All of my iPhones I have had previously are 2+ years old, and when I take the case off them, they’re literally looking spotless.
Very good. You want to treat objects like that, it's your prerogative. You are doing exactly what the people you mention do: what you want with your object.
