yes. Ben boy undoubtedly did not get all of the details correct.
ex; even his own Mother disagrees with his "hammer" account and what happened.
so yes,..Ben boy did not get all the story "details" correct, he told of a synopsis of the (hammer) event but undoubtedly not all the "details" because a person in the same event (his Mother) has an entirely different account,...so,....
that would make Ben boy a LIAR because he did not include ALL of the relevant details. one main LIE,...he totally lied about what actually happened.
maybe Ben boy viewed the event in a alternate reality,...the teapuker reality.
