someone_else_again: we cannot change people's behavior, only our reaction to it.
Erimitus: our reaction the another persons behavior can influence how that person behaves in the future.
its all in the mind. No really everything external is an internal representation in our mind.
Anyway that a side.
You can either blame yourself. Sometimes its good to re frame so you believe the other person is at all fault.
If you always ask yourself what you dud wrong then correct you will improve and get further towards being your best self.
An example would be if im sparring and I get beaten. I have two choices, I can either tell myself my opponent was better and leave it at that. Or I can tell myself my kicks could of been better and so could my parries. I then go and improve these areas and next time I spar I get a different result.
parties either view is right or wrong, its just a perception. However one view serves no purpose but to limit you.
