I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: The Way Home Movie plot: The story begins on a fine summers morning, when Sang-woo (Yu Seung-ho) and his mother board a bus to the country. It is soon clear that the unsophisticated rural passengers annoy the seven-year-old urban boy. His mother is taking him to live with his 78-year-old mute, but not deaf, grandmother (Kim Eul-boon) while she looks for a new job after a business venture failed in Seoul. Eventually they reach their destination, a dusty bus stop in the Korean countryside near an unsophisticated village.By now Sang-woo, who has arrived with junk food and toys, has no intention of respecting his mute grandmother especially as her house has neither electricity nor running water. His mother apologises for leaving the boy, telling her own mother it will not be for too long before leaving on the next bus. Alone Sang-woo ignores his grandmother, not even wanting to look at her and even calling her a byungshin, or "retard". Next morning, his grandmother starts another day. She goes down the hill to get clean water and washes her clothes at the river. She also tends the melons that she will sell at the market.One of the Grandmother's neighbours is a hard-working country boy who attempts to become friends with Sang-woo, who declines until the end when he apologizes for making fun of him. The other is a young girl who Sang-Woo falls in love with, but she is more interested in the country boy.The grandmother, who also cares for her old friends very much, lives a simple and humble life. Eventually, from constant play, Sang-woo's Game Boy runs-out of batteries so he asks his grandmother for money for new ones. But she is poor and has none. Selfishly he teases her, and in an intolerant manner throws away her shoes, breaks one of her vases and draws graffiti on her house walls.When this fails to get money from his grandmother, Sang-woo steals her ornamental hairpin to trade for batteries. He then goes off to find the shops. When he finally finds the right place he attempts to trade the silver hairpin but instead of getting batteries... My question: What does the grandmother sell at the market?
