The other day, Tropea left Boko at home for a moment so she could walk her sister Isabelle to school. What Tropea didn't realize, as she stepped out the door without her keys, was that her sister had set the door to lock behind her.
Upon returning, Tropea realized she was unable to get back inside. She wasn't the only one concerned.
"I got to the front door and Boko could hear me trying to get in," Tropea told The Dodo. "He started crying and scratching at the door."
