Why do people perceive those who are optimistic in such a bad way?

It amazes me when I see someone become so angry, and judgmental when they hear or talk with someone who’s optimistic.

Why is it when someone looks on the brighter side of things, it’s looked at as stupidity?

Instead of holding on to the past, instead of stressing and worrying about something that you can no longer change — optimistic people tend to look at the brighter side.

For example, I myself tend to think of the lessons — what I’ll learn form such situation, why this situation happen and how I could prevent it in the future; also I am grateful to be able to make it out of those situations alive, so I can tell those about it and maybe even help them prevent it.

Control the controllable — their is nothing beneficial from negativity, but their much to gain from positivity
