I actually was saying far worse things in the car until a few minutes ago.
I took the tram/metro/train combo back out to the airport this morning to pick up my rental car. Took a while, mostly because the train was late. Then I couldn't find the Alamo desk in the terminal at first. Once I got the car, I couldn't start it. After I worked that out, I fumbled around trying to figure out just how the unfamiliar manual/automatic hybrid transmission worked.
And then things got complicated. Let me say at the outset that I should have gotten a map before leaving the airport. I thought I'd be able to get back to the hotel, but I ended up driving in circles for far too long, passing familiar landmarks, but then being led off course by an apparent maze of Barcelona streets. When I finally stopped to ask directions, I got on the highway, only to realize it was going the wrong way. Each of two moves I made to turn around only took me miles out of my way without a turnaround opportunity in sight. I was screaming in frustration!
Once I settled down, I figured out how to get back to the hotel, though I had missed the check-out deadline by over an hour.
No worries now, I am heading out of Barcelona.
