On the last day we were in New York, we went to the Empire State Building. First my dad didn't wanted to go, because about 3,5 years ago, we also went there. But I said 'Dad, it's your birthday and how many (Dutch) people can say that they were on the Empire State Building on their birthday'. He said I was right. So we still went. Only the stupid thing was that we had to wait really long. But it was worth it.
