Last evening, I went to teahouse with my best friend Susan. Before the tea was serving, we talked to each other happily. When the waiter went to us with the tea, we didn’t see him. Unfortunately, Susan rose her hand to comb her hair just while the waiter bent to put the plate on the table. His hand hit the cup, and the tea was spattered (溅) on her trousers. In my surprise, instead of complaining , Susan smiled, “ So lucky that it’s not on my shirt, and I can’t even clean it.” Her words were very inspired. We can’t foresee what will happen, but looking at it in a positive way can make us be happy
