During my trip to Spain, I joined a local fiesta. I tried to dance the flamenco with the locals. But I had no idea what I was doing. I just flailed my arms and legs around. Everyone around me was laughing, and I was laughing too. It was a great moment full of joy and humor.
In my travel story, the most interesting part was when I was in Japan. I entered a traditional onsen (hot spring). But I didn't realize there were certain etiquettes. I accidentally splashed water around and got some strange looks from the locals. It was embarrassing at that moment but very funny in hindsight.
