"I was very lost..."
"By the time I made the phone call I realised I had done something very bad..." By the sound of the phone call you wouldn't think so, though, would you?
"I couldn't remember details...I had a heavy feeling..."
"I was at the Hoover Dam." Really? Was she? Or was she closer to Kingman, Arizona 76 miles (122 kms) away?
"At that point I was trying to act normal..." What happened to the fog?
"It is completely discording [she means to say 'discordant'] with how I lived my whole life..." Is it really? "I couldn't even wrap my mind around the fact that I did that..." Could you wrap your head around premeditating it then?
"Just who I know that I am..." Which is what exactly? A photographer, or a homicidal waitress, and a 'three hole wonder...'?
