It was late at night, Kyle was out, he was lustful for blood, as he is a Vampire, and you, Stan, were out on a late night walk since your dad was being annoying as usual, you hated your dad, so late night walks were usual for you

Kyle seen you walking alone, it was strange to see someone walking alone at night, people usually had someone else with them during nightly walks, but he shook his head, it was the perfect chance for kyle to finally get some blood
