ОтветитьУдалитьShe had to phone Tom. He was right. She - and the Universe itself, speaking in the voice of God as Judge in her - was absolutely fed up with all of those detestable idiots around her.
“Everything is on you”, Tom said to her that morning. “If you’re not calling, we’re not going anywhere. We’re not taking guns, we’re not stealing my father’s car, we’re not doing anything”. “Is he trying to shift the responsibility on me?”, Linda thought at that moment. Deep in her soul she hoped that something, someone – some miraculous event – will pull her out of that dark tunnel she’s fallen to...
But when she came home and sat in her room, ever and again anxiously looking at the window for signs of that force, her father, drunk as always, stumbled into the room and started shouting at her with no particular reason. She ran out and locked herself in the toilet. That was the sign. The Universe wanted her to commit the shooting. She opened the messenger and started ringing Tom. Now she knew. Although she was afraid, Linda knew she had to make the call.
