It's not easy for everyone to be away from home. You are lucky to meet such a good landlord, but you should also be a good person. Put yourself in her shoes and spend New Year's Day with her. You can give her a gift. Here are some suggestions:
1. Bring some snacks, fruits, or a bottle of slightly better wine to eat together, which is also a courtesy.
2. Give her a bouquet of flowers and a creative gift, such as a crystal music box or a big teddy bear, which can increase the atmosphere of her home.
