What is the most special thing you have ever done for your dad?

My daddy tried to be a pilot one he was younger, but he had problem with the test and couldn't passed them. So for his birthday my family, and me took he to do a flying class. I was the one to enter with him to the plain.. He was so exited and i was very happy to see him like this and be a big part of that. The flight was a bit scary but it was worth it!
