Anakin hadn't had any at the Jedi Temple either, but he'd spent his training years on Yavin IV in an uninhabited forest surrounded by rocks. Ahsoka had had a formative childhood in the biggest city in the universe. He couldn't imagine not sneaking away. Maybe Jedi were better behaved when they weren't Solos.
