I really liked this. Well done, probably very, very realistic-- I really love the "liar liar liar liar she asked just this morning why he had to come" that was really morbid and sad. My favorite line:
"The cold weather had chapped his lips, made them dry, made his voice crackle like autumn leaves, and you couldn’t stop seeing the murderer in him like you knew he saw you as a cheater."
Nice work.
