I dont understand...
ANY caring father would want to find out what exactly happened to their little girl, and not just benefit from the occasion to help make there stereo system louder. ANY caring father would donate to private doctors to find the exact cause of death, and then donate to help cure it.
Second of all, if this is for a system... then how did hannah know what was "boom"?? That means he already had a system for her to listen to. So why the change up? Let me guess, he got his *** kicked at the local comp that night his girl died, came home...already upset at his loss, and found his little girl and decided in her memory... I NEED TO BE LOUDER.
Wherever you live has ****ed up theories and views on life.
