She Had Lied To Him
Apparently, Lise had dropped out of the university months ago without telling him anything about that decision. She did not make it through her first semester and instead of telling him, she ended up lying to him all this time.
She was keeping it from him all these months. Even worse, Lise didn’t bother telling him where she was staying at this point. Dale was overcome with worry and concern. He was saddened by Lise keeping this a secret, but he was even more worried about her safety.
