该句使用定语从句who provide strength修饰朋友的定义。
I smile often, but I am not always happy. When things do not go my way, I long to escape the person who causes me pain. Yet, moving on feels too difficult; preoccupied with caring for you, I have forgotten how to leave. Time and again, I have grown accustomed to your presence and to the heartache of loving you.
Humans form society, and society is like a giant chessboard where every piece plays a distinct role. In life, some occupy high positions with wealth and honor; some scheme behind the scenes to deceive; some charge ahead unstoppable; and some sacrifice silently, their contributions seldom recorded.
True glory lies not in never falling, but in rising every time we fall.
Life is not about waiting for the storm to pass, but about learning to dance in the rain. Friends are those who provide strength when all else is lost. As we grow wiser, we realize life is about more than just love; human connections are complex and interdependent. Many things are more important than romance, and sometimes, certain feelings are better left unsaid. In youth, we love passionately; with age, we love with restraint.
Those who sow in tears will reap in smiles.
Do not dwell on how beautiful the past was, nor ask how glorious it once seemed.
我常笑，却未必常乐。若不如意，便想逃离这令人心痛的你；若要移情别恋，却又难如登天。只顾着心疼你，却忘了离开，一次又一次，已习惯有你，习惯了心疼你的一切。
人组成社会，社会如同一盘大棋，帅、士、象、车、马、炮、卒各司其职。生活中的人亦如棋子，有的位高权重、荣华富贵；有的幕后筹谋、欺诈他人；有的横冲直撞、所向披靡；有的默默奉献，功勋却难寻。
并非从未跌倒才是荣耀，每次跌倒后能重新站起，才是真正的光荣。
生活并非等待风暴过去，而是在雨中跳出最美的舞。朋友，是最后能给予你力量的人。人一旦懂事，便会明白世界并非只有爱情，人与人之间相互制约。很多事情比爱情重要，有些情，说透了反而不如保持沉默。年少时不懂，爱得轰轰烈烈；懂了，却爱得小心翼翼。
含泪播种的人，终会含笑收获。
莫问往事有多美好，莫问曾经有多辉煌。
