Dina is a 7th-grade student who loves painting with watercolors every weekend. She usually spends about two hours on Saturday afternoon painting landscapes in her bedroom. Painting helps her stay calm and creative after a busy week of studying at school. She buys watercolor paper and paints once a month using her own pocket money, spending around Rp25.000. However, she always sets a timer so she does not forget to do her school homework on Sunday.
