Why did Lucy not mean to hide in the wardrobe?

Lucy's intent was to snoop in the wardrobe... she was curious, nothing more.

She stayed behind because she thought it would be worth while trying the door of the wardrobe, even though she felt almost sure that it would be locked. To her surprise it opened quite easily, and two moth-balls dropped out.

Looking into the inside, she saw several coats hanging up - mostly long fur coats. There was nothing Lucy liked so much as the smell and feel of fur. She immediately stepped into the wardrobe and got in among the coats and rubbed her face against them, leaving the door open, of course, because she knew that it is very foolish to shut oneself into any wardrobe. Soon she went further in and found that there was a second row of coats hanging up behind the first one. It was almost quite dark in there and she kept her arms stretched out in front of her so as not to bump her face into the back of the wardrobe. She took a step further in - then two or three steps always expecting to feel woodwork against the tips of her fingers. But she could not feel it.

Was Lucy more frightened or curious
