求一道托福口语题的Sample answer。

我来！
*Well, in my opinion, my 20th birthday, my first surprising party held by my friends, surprised me most, and I have 2 main reasons for that. First of all, I was amazed by the definition of true friendship as some of my old friends from South America traveling 20 hours by air coming to celebrate my birthday, who attacked me dramatically with a birthday cake. Another thing that was surprising to me was that they took a photo of me which made the whole occasion unforgettable. Finally, they sang a birthday song for me according to western tradition, which is totally out of my expectation. ^
