When I go on vacation, I will go to the Bahamas. But before I go to the Bahamas, I will pack my bags and prepare to go on to the plane that will fly me there. After I pack my bags, I will go into the car and drive to the airport. And after that, I will wait.
I will wait a very long time, because the plane has been delayed.
...
I'm still waiting.
I didn't see this coming in my plan, but here we are.
Sitting on the bench.
Waiting.
Once I am done sitting on this bench, I will get onto the plane.
But the plane is still delayed.
So therefore, I will sit on the bench.
I did not plan this.
Sitting on the bench next to a bunch of strangers is not how I wanted to spend my time.
I planned to go to the Bahamas and relax on the beach with a fruity coconut drink and a little umbrella.
But here I am, on the bench.
And I will sit and plan some more.
Maybe daydreaming will help me pass the time.
I will daydream.
Because the sun will be on my face, and the sand will be in between my toes, and I will not have to worry about this stuffy work outfit for at least three weeks.
I will have my fruity coconut drink with it's tiny umbrella, and I will NOT worry about my flight being delayed.
Because when I go on vacation, I will be in the Bahamas.
