Impolite as the language might be, its very true-ironic. Wanting things to be better, trying/wanting to help, bringing them out, leaving-they get offended after how they acted, in defense mode, try to justify/blame/hurt you more. People like this are sick cowards when they trash someone/what's most important in their life.
