Manners seem to be a thing of the past! People are encouraged to always speak their mind and be assertive, but in some people it just comes off as rude or obnoxious because they are demeaning in their delivery.
I have made many observations of people who either treated me, my kids or other innocent seeming people with aggressive and angry words. I tend to think when someone's life is going wrong they have a bad attitude and want to take it out on others who seem to be doing well. I have always wondered why I have to be the recipient of someone elses misplaced anger.
This may just be me, but when life hands me a raw deal I don't go around angry at the world, in fact, many would never know there was a problem. Kind of just how I am, hate that out of nowhere sabatage so I won't do that to anyone else.
