New Year's Day is the first day of the new year. My sister is in a bad mood. Of course, we should make her happy as soon as possible. We can't let her enter the new year with a bad mood. Give her a small gift. Here are some suggestions:
1. Since you have a quarrel with your brother-in-law, I think you can talk to your brother-in-law and buy a small gift for her with him. I think any gift will make her smile happily.
2. Give her a creative gift. You can give her a box of DIY chocolates and make your wishes. The delicious chocolates plus your wishes will definitely make her very happy. You can also give her a crystal music box. Good music will make her feel better. The beautiful music box will also make her love it.
