A blamer is someone who does not take responsibility for their actions and claims that everyone else is to blame. Do not let these type of people control you. Step up and call them out on their bluffs and actions in hopes that it will deter them from being blamers in the future. Do not be afraid to defend yourself in order to pull out the truth and show everyone how these people really are. Try to avoid a fight, but if a fight is inevitable then at least have some good comebacks in case they try to pin the blame on you.
