Two simple words "thank you" have made a big difference to thousands of fireman in New York City．
Savannah is girl form Texas．"I was trying to think I could help them out，"she says．After hearing about sacrifices（牺牲） made by fireman，she （move） by the risks they face， Savannah made 200 thank﹣you cards for them．"I want to show how much I care about them．"
"I told the fireman thank you，"Savannah recalls．"They're always there to help you．"
Savannah decided （keep） making cards．For the next seven months，she woke up early to paint and color and cut．In that time，she （send） 1,600cards with bite﹣sized candy while meeting her （hero）．Soon，fire station started thanking her．
Once too shy to give a speech at school， is now easy for Savannah to speak regularly to fireman and school students．She is quite different what she used to be．
"She's saying how （thank） she is for them!" Savannah's mom，Debbie，says，"Savannah sees that stepping put and doing something can really make a difference．"
