When Valerie is writing in her diary, she sometimes writes with her left hand, sometimes with her right, suggesting some shots were flipped.
In the beginning Valerie says that she lost her virginity in 1993 and some minutes later she says "since that passed 14 years"; the engraving on her grandmother's grave says: "Marie Tasso 1934-2006", implying there are only 13 years between 1993 and 2006.
