Isn't it odd that people like that don't realize at some point in their lives, how abrasive and unloving they appear to everyone around them and know how their behavior can so negatively affect others? They never seem to reflect a drop of human compassion or true caring for anyone else, EVER.
in observation.. I think.. that people like that. have a low self esteem .. and an ego problem.. Kind of like ( the man of small stature ) Trying to use his words to bring others down to his level.. OR the little dog. with the big bark.
In one case ..the person grows up and has no friends, and in the others.. the dog goes to the pound.
