Maybe I am out of the loop here but, there are some people that decide to be deliberately cruel. Especially those who you work with everyday. I try to check myself every chance I get before I step to someone so that I won't disrespect them or insult them in any way. I just don't understand why others don't do the same.
I do have a sense of knowledge and understanding on the fact that we can be in our own moment, unaware of how we effect people sometimes. But it amazes me to witness this type of behavior amost everyday.
I just don't get it.
