That warm day was the only day of the week without rain．I opened the door,took a seat and began to enjoy the wonderful sunshine．Suddenly,I noticed that the house near mine had been sold．An elderly lady was in front of the door,with some beautiful flowers beside her．I walked to her．She looked to be in her early eighties and had the prettiest white hair．

“Hi！My name is Karmen,”I said smiling brightly at the old lady．She smiled back and said,“Hello,Karmen．I ’m Henrietta．”Her voice was very strong for someone at her age．Later，I learned she was alone and had no family or relatives to help her．From that day on,I often visited her and helped her with her housework and sometimes she gave me some delicious food．A year passed,and I considered Henrietta to be one of my best friends．

One day,I walked over for my morning visit and knocked on the door,but there was no answer．I knocked again,and she still didn’t turn up．So I let myself in,using the key she had given me．I checked her living room and then her kitchen．I finally went into her bedroom,and she was lying peacefully on her bed．Beside her there were two notes．One was her will（遗嘱）,which said all that she had would be given to me．The other was a thank-you note．I went to her bedside and cried sadly．

Though several years have gone by,I still miss her deeply．Whenever I look at the beautiful flowers in front of her house,I remember the wonderful friendship we had．
