What does Bing Xin mean by saying, "Love is on the left, sympathy is on the right, and we walk on both sides of life"?

Bing Xin said: "Love is on the left, sympathy is on the right, walking on both sides of life, sowing seeds at any time, blooming at any time, decorating this long journey with fragrant flowers, so that pedestrians who wear branches and brush leaves will not feel pain, and there will be no tear drops, but they will not be sad." This love, this friendship, together with a family affection, will definitely make full of green, the tree of your life, shine with a brilliance that can be read at a glance, whether in the sun or in the wind and rain. Affection is a kind of depth, friendship is a kind of breadth and love is a kind of purity. Affection is an unconditional and unrequited sunshine bath; Friendship is a powerful understanding bank, which can live safely at any time; And love is a mysterious boundless, which can make songs forget their feelings and make tears shine. "It's a pity that family, friendship and love are indispensable in life; Poor is three missing two; All three are gone, and they live like dead! " (Liu) Being able to appreciate the depth of family ties, the breadth of friendship and the purity of love is a life worthy of the name.
