Why do you think a voice teacher agreed to give Marian lessons without charge?

A voice teacher may have agreed to give Marian lessons without charge out of a desire to support and nurture talent, especially if they recognized her potential or passion for singing. Additionally, the teacher might have felt a personal connection to Marian's situation or wanted to give back to the community by helping someone in need. Lastly, it could also be a way for the teacher to gain fulfillment from mentoring and fostering the next generation of artists.
