Buy someone's coffee.

　　為他人買杯咖啡

　　It's just coffee -- no one needs coffee, so this doesn't really matter, right? But what if you knew that a $2 cup of caffeine could change someone's day, week or their whole perspective? Boom: That cup of coffee just changed the world. Welcome to the Random Acts of Kindness movement, where nice things happen just because nice people do them. You don't have to, you don't necessarily need to, but you can -- and it restores people's faith in humanity. The best part? They pass it on.

　　只是杯咖啡而已——沒人必須要喝咖啡，所以也無所謂，對吧?但是如果你知道2美元一杯的咖啡可以改變一個人的一天、一周甚至整個人生，那你會怎么做?哇，一杯咖啡改變了整個世界。歡迎參與“好事隨意做”活動，就是因為好人做好事，好事才會來。你不一定要做，你不必一定做，但你能做得到——這樣會讓人們重新相信人性。你猜最好的部分是什么?人們會把它傳遞下去。
