I went to a big concert. I went to a big concert of a Japanese idol group with my wife. We didn't have tickets for that but also didn't know about that they would hold the concert in my city. When I knew it was just 3 days before it and I got the tickets the day before it. The reason why is that my wife's sister had the tickets but she became unable to go there due to her job and she gave us them. When she gave them, she told us that our seats were very far from the stage. It was true. The idol is one of the most popular one in Japan and the concert was held in the baseball dome. The dome was fully filled with 40,000 people. It has five floors and our seats were at the last row on the fifth floor. Nobody was behind us between these 40,000 people.
