对于真正的朋友，不要吝啬关心的话语。一条短信，一个问候，主动一点，不要太斤斤计较

参考英文：

For a true friend, don't be stingy with words of concern. A text message, a greeting, take the initiative, don't care too much about who is better for whom. The two sides of friendship must pay more. It doesn't matter who that person is. What matters is that your relationship continues.
