>> i was working in my yard to protect my earmuffs on to protect my hearing from the mower. i was facing downhill and the attacker came running, i never saw him, the weird thing is i haven't talked to him in ten years. >> i spoke to him about what the motive might be and what might be inside the man's head. you heard him say he hadn't spoken to his neighbor in almost ten years. he thought about it and he said you know, i really don't know but several things come to mind and they are political. take a look. >> you don't have any idea what was in his head? >> i didn't before the attack because we had no conversation. after my ribs were broken and he said things to me to indicate why he was unhappy. i think -- to me the bottom line is if someone loves you, is it really justified for any reason? i think the more people belabored, was it about yard
