Calla was delicate, he wasn't sure if she was just really kind and liked to cook or if she thought something special of him. If he was wrong and told her something off the mark, she might just hide in her room and never come out again. He'd rather see her happy with someone else than never see her again because he embarrassed her too much. Maybe his mother would have something to say on this but in the meantime, he'd rather not do anything.
