It's the default for some and it's very sad as you say, especially considering there's far better ways to think or feel. As you say, it's about how the person is generally and sometimes it's not something they can control either. I guess it's up to others to help guide them through, help them see from different perspectives.
Italy...I had some amazingly great experiences there over the several visits I've made...a few debacles though...but coffee and cannoli's made it all better. 😁
