This is true because any gambler who is with his right senses will never blame anyone for his or her lose, how can you possibly blame someone for losing when the person is not there with you when you were seriously making your prediction. Though sometimes you May be getting opinion  from people around you or friends more especially in offline gamble but you have every right to stick to the one that is suitable for you. And Yeah, that's how it is sometimes when making a prediction your friends may be bringing suggestions and sometimes you can get distracted this is why I don't team with friends when making prediction I don't like taking other people's prediction, though I can remembered taken my friends suggestions and it failed but I don't blame him for that because I know that gambling is just a game of luck.
