I only wish I hadn't!I suppose this is something we may all have been guilty of,consciously and/or unconsciously. Why? Well the reasons can be many. A overworking sense of humor where nothing is sacred and no one spared in the name of laughter, arrogance, the lack of self esteem that makes you want to put down others in a bid to seem smarter,wittier,cooler etc. Ignorance and lack of manners, the list goes on.
Of course to some it maybe that they genuinely don't realize how bad a trait this can be, mocking and taking the mickey out of anyone and everyone, but to others..well they just don't care to realize!
Kudos to those who see the error in their ways, and seek to change themselves.
