You had a beautiful friendship. Maybe more than a friendship. And I envy you. In my place, most parents would hope the whole thing goes away, or pray that their sons land on their feet soon enough. But I am not such a parent. In your place, if there is pain, nurse it, and if there is a flame, don't snuff it out, don't be brutal with it. Withdrawal can be a terrible thing when it keeps us awake at night, and watching others forget us sooner than we'd want to be forgotten is no better.
We rip out so much of ourselves to be cured of things faster than we should that we go bankrupt by the age of thirty and have less to offer each time we start with someone new. But to feel nothing so as not to feel anything—what a waste!
How you live your life is your business. But remember, our hearts and our bodies are given to us only once. Most of us can't help but live as though we've got two lives to live, one is the mockup, the other the finished version, and then there are all those versions in between. But there's only one, and before you know it, your heart is worn out, and, as for your body, there comes a point when no one looks at it, much less wants to come near it.
很多事does matter，包括feeling，no matter pain or happiness，不是一句不要放在心上可以解决的。希望以后自己能记住，对待生活中的大事小事，要用心要认真，不要怕被伤害。真正害怕的是三十岁后的自己变成一个老女人。
