Kyle is my big brother．For eighteen years，I felt that Kyle was my enemy．In fact，I found it ridiculous that people thought older brothers looked out for their sisters，protected them and fought off their sisters' bullies （恃強(qiáng)凌弱者）．Huh？My brother was the bully．
   When we were little，his fights with others caused my black eye，cuts in my lips and even a nosebleed or two．I often wished I were an only child!
   Time flew．We ended up attending colleges two thousand miles apart，yet，strangely，that's when we began communicating．Through e-mail，we kept in constant touch．Mostly I complained about serious homesickness，impossible roommates，difficult classes，and…dating．I felt I lost myself．At a particularly low time，I cried to Kyle about my injured confidence，my broken heart，and the particular jerk （蠢人） who broke it．
   And that's when the package arrived．
   "What's this？" I thought as I tore into it．The box revealed a sweatshirt． "Phi Delta Theta？That's Kyle's frat （兄弟會(huì)）．" Kyle was the president of the frat house．Why would he send this？I put it aside and dug deeper．A pile of letters．And they were all addressed to me．I opened the one on top．
   "Katrina，" it said， "your brother showed me your picture and I think you're awesome and beautiful．" I rolled my eyes． "Yeah，sure．" I opened another letter．And another．Eighteen in all．
   Each one was from a different guy．They complimented （恭維） me．They invited me on dates．And they tried to convince me to make a trip out to Knox College and meet them．
   I loved it．I didn't care about the motive．And mostly，I loved the idea that ray big brother had pulled it off．I picked up the phone．
   "Kyle，the box came and I can't believe what you did．" But Kyle wasn't accepting compliments． "Oh，" he said， "I was just tired of reading your over-sensitive e-mails．"
   Big brothers，I decided，really did protect their sisters．And mine fought offthe biggest bully I'd ever met．Now I return to my true self，full of confidence．
