Such people are to be pitied - seriously.

We have all met people who are constant whiners. Mostly we deal with them by avoiding contact whenever we can. In the worst cases, they get frustrated by being perpetually ignored and do something undesirable to force our attention.

Everyplace they go, all day every day, everyone they meet reflects their negative attitude back at them so they are doomed never have any pleasant experiences. I really do feel sorry for them but there's nothing I can do to help them. They have created their own spiral down to hell.
