So, her sons are actually trying to hit each other with Bricks and then the Mother goes flying to her death. I'm going to go out on a limb here and say the family was somewhat dysfunctional. If the family was this dysfunctional it was probably the Mothers fault, if she had raised them properly they would have probably been able to resolve the dispute without bricks and she'd still be alive.
So you think that the cause of the family dysfunction would automatically be the mother?

oh dear…
