I don't remember how many Valentine's Days we have spent together, nor do I remember how we celebrated them. Perhaps because we are often apart, we sometimes quietly forget; although we lack the luxury of 999 roses or the drama of a "must-marry-you" vow, I feel our life is simple, real, and sincere.
Life consists of 5% excitement, 5% pain, and 90% ordinariness. Only in this way can one learn to enjoy life and appreciate the purest beauty of human nature.
不记得我们在一起度过了多少个情人节，也不记得我们是如何度过这些日子的。或许是因为常常不在身边，有时也会悄然遗忘；尽管没有999朵玫瑰那样的奢侈，也没有非你不可的惊心动魄，但我感到我们的生活平淡、真实且真诚。
人生由5%的精彩、5%的痛苦和90%的平淡组成。唯有如此，才能做到享受生活，体会人性的至纯至美。
"I remember a warm afternoon, sitting alone in a sun-drenched room."
"The roses have bloomed again, as elegant and fragrant as that year."
"Any beautiful yet painful memories have become the melodies of yesterday."
"A gentle breeze passes by, and the beautiful scenery disappears beyond the window shrouded in night."
"Every footprint holds a memorable memory from the past."
