How does Rosa Hubermann show her love to Liesel?

Rosa doesn't show her love openly. She is a bit abrasive and insulting, both to Liesel and Hans. She, however, dip lays her love in more practical ways. She always makes sure they are fed and taken care of, even in the most dire of circumstances. She protects them and takes care of Max, and other stowaway Jews, who mean so much to Liesel and Hans.
