My terrible trip to the US

I have traveled many times, but I have not experienced such a terrible trip. My trip started on the airplane to go to Seattle two weeks ago. At the airport in Seattle, my host mother and father were to meet me. I was excited and looking forward to seeing them, and imagined the great situation of the meeting in the lobby. In my brain, I and my host family made a conversation pleasantly. As I went to the arrival lobby, I could see a few people waiting for the passengers. I thought I could find my persons waiting for me, but nobody has my name plate in their hands. Although I felt fear, I decided to wait there for a while. I waited for one hour there, however I could find nobody. Indeed, I lose my temper and my feeling went down. I called my agent and asked how to deal with this trouble. However, such a trouble could not be solved so fast, I was waited there for one hour. The cause of the problem was that my host mother brought a wrong name plate. One hour later, host father came and picked me up by car. While I was waiting, I felt quit fear and loneliness. Totally, I was waiting for three hours at the lobby in another country! I do not want to experience such a bad situation in my trip. I will never forget this experience.
