An Embarrassing Experience - draft two

There was an embarrassing experience of my foreign travel about seven years ago. At the beginning of the summer vacation, my grandparents and I took a trip to Hong Kong. On the second day of this travel, we went to a big and beautiful shopping mall. In addition, the inner decorations of the building was so splendid that attracted my attention. In the meantime, I even didn't take notice of the movement of the traveling group. And I just followed the traveling group in front of me. Subsequently, I found that I followed the wrong traveling group and they were laughing at me. Then, I became not only nervous but also hurried. I only thought this sentence "Where? Where are my grandparents?" Fortunately, they didn't go far away, and I could easily find them. That was the best thing no more on that day! After this incident, I will pay more attention to what I should pay, and never do the same stupid thing again.
