If someone is hopelessly optimistic, or a pollyanna type, they are described as looking at the world through "rose colored glasses." Nowadays we don't have an overabundance of these people.
Now there are no shortage of another type. They see nothing right with the world and it's always someone else' fault. They can never see much good in most people, and if they do acknowledge any good, "there's always an ulterior motive." These people are the type who brighten up a room by leaving it. These are the type of folks, whom I describe as those "looking at the world through crap colored glasses."
I like to think I wear glasses with a small tint of rose coloring, otherwise clear. Realistically, I've been wearing glasses since I was 11 years old, so they are a little dirty most of the time.
What color glasses do you view the world through?
