     Last evening, I went to a teahouse with my best friends Susan. Before the tea was serving, we talked

to each other happily. When the waiter came to us with the tea, we didn't see him. Unfortunately Susan

raises her hand to comb her hair just when the waiter bent to put the plate on the table. Her hand hit on

the cup, and the tea was spattered(溅洒) on her trousers. In my surprise, instead complaining, Susan

smiled, "So lucky that it's not on my white shirt, and I can't even clean it."His words were very inspired.

We couldn't foresee what would happen, but looking at it in a positive way could make we always happy.
