She would only use it if what she is facing is a true threat. She normally uses magic to deal with less dangerous threats and no magic at all when dealing with mundane things.

To waste time she tends to spend time on her grapes. Or read books. Hell, she just does stuff most people do.

So she tends to reserve her true abilities for something that would actually threaten her life or things on a grand scale. She tries to avoid falling into the I have to help everyone and anyone at all times and only deals with threats that is outside human capacity.
