As sixth graders, kids were separating into groups, but I wasn't sure where I belonged．
Our teacher gave us a task called "secret friends" for the coming week．We were supposed to do nice things     our friends without letting them know who was doing it．We could leave  encouraging notes or cards either on their desks or in their bags．Before doing the task, with our eyes closed, from a basket, we        a name of a classmate who we were to secretly befriend over the next five days．
Soon, the task was turned into a competition of giving       instead of notes．Everyone was getting cool presents except me．My friend exactly       what the teacher had told us．So I received nothing but hand-made cards with nice words about me．
On the last morning, I finally got a package．When I       it, the girls around all       ．It was an "old lady" gift．My face went red．
I tried to forget about the shaming gift, but when the same girls       it again during the break in the bathroom, I joined in, "How stupid! My grandmother wouldn't       want it．" The girls laughed at my words and went out of the bathroom．Washing my hands, I let the water run through my fingers       I thought about my words．It wasn't       like me to say things like that．
"I'm your secret friend．" It was Rochelle．" I' m sorry about the gift," she said to me, tears running down her face．
From a poor family, she was a target(目标) at school for those with rich parents．Yet she just took all the terrible treatment silently．
I was sick to my stomach as my       words ran through my mind．She had heard everything．How could I have been so unkind?
Later I learned she had felt bad all week about not being able to leave me any cool present and her mum had given up her only luxury（奢侈品）．
And I had destroyed everything for her．
I told her that I had only said those things to try to fit in.
"We aren't that different from each other, are we?" She smiled understandingly．Her simple      , spoken from her heart, found their way straight into mine．
