My sister is lovelorn. How can my brother comfort her?

Sister can take her brother out to play, eat delicious food and enlighten him more. If a friend is lovelorn, this is the time to need your company. So you should pay great attention to your words. Try not to find some useless topics. Your intention is to adjust the atmosphere, but your friends may find you annoying. So you are responsible for what your friends want to say and do. Don't take the initiative to talk about things between their lovers, whether they are happy things or bad memories, don't go.
