It's very common that we often notice in life either we blame or got blamed for no reason. Life's been so busy that you hardly get time to care for somebody blaming you for no reason but it's real pain when you get blamed by somebody who means a lot to you and the one who you care for.
Well no one in this world wants any blame on himself. so he tries to blame anybody around him to
Get rid of possible blame to be pointed to them: It was quite often my case too that my elder brother often blamed me for everything he destroys.. and funnily it saved him a lot time when I didn't started talking, he blamed me for everything thus nullifying any possible shout by mom. It's a sweet blame-game that everyone goes through once in life. Sometimes people blame others not because they hate them, but it can turn to a serious issue too. so it's always best to be careful before pointing somebody.
Blaming without a good reason: Sometimes blaming is not only to shield himself but put you i trouble which is disgusting. You always are busy in your own work, and has no time to take a head up and get blame for something you are never indulged in. Though these are often promised by TV series here in my country, but YES these also happens in your real life. As in office how your good-at-everything collegue blame if the project goes bad.
Well there might be as many reasons for anyone to blame you maybe for revenges like for the huge-as-hell bite you took from your friends pizza or for the penalty shot you kicked kicking your friends ass but missed the goal xD.
How do you try to avoid blames on you?
You can't expect anybody to change his mind and stop blaming on you. It's how they think or how they show that they are unable to handle the defeat or loss themselves:
Be clear in your words and works: Yes, if you make everything clear then there are less chances for anybody to blame on you when you never did that. Don't make a vogue or unclear image of the work or things you are in when there are chances for you to get blames.
Conclusion
It's very important to know anybody well before you talk or influence him. It undermines people even can lead them to suicide. So please think twice before blaming somebody. A small life issue can make somebody lifeless. Nothing is more important than life.
