I'm not First Class

It was Chuseok weekend, my first holiday in Korea. I had been invited to spend the weekend with my friend Sangwon in Incheon. However, we would visit his parents in Dangjin first, spend a day in the area and then all drive to Incheon and meet all of his relatives. I set off for Dongdaegu station so I could catch the KTX train toward Daejeon. I would make a stop in Cheon Ansam where Sangwon would be waiting at the station for me. The time as about 8:40 that I was supposed to leave from Dongdaegu station. By the way, Dong means east so it's the East station in Daegu. I was ready for my weekend and next I had to figure out my gate number. I looked for the number and finally found it after asking someone.

The boarding time approached and the train came but I realized that the doors in front of me had first class on them. At first I was confused and I said, "Wait a minute, I'm not first class" "Is this right? "It's the right train but." the train stopped for a brief moment maybe 30 seconds. As soon as I realized that I was supposed to be in a different car, it was too late. The train had already started moving. I had missed my train. Uhh. I couldn't believe I did such a thing considering I knew it was my train. I then realized I should have just got in the first class car and walked to my car. Well I thought about the trip and I panicked at first but surprisingly I calmed myself down. I went upstairs and bought another ticket and called my friend and explained to him my situation. It was embarrassing but I can laugh now. I may not have been first class but I was a passenger. I guess I just forgot, lol.
