Describe something important you once forgot to do.
You should say:
what you forgot;
when and where this happened;
why you forgot it;
and explain what the result of your forgetting was.
There was a time that I forgot my camera on the train.
It was about two months ago when I was on my way back from Sanya, a beautiful place where I just had my summer trip. I was quite drowsy when the train arrived at my station. When I heard the train announcement, I quickly grabbed my backpack which was placed on the luggage rack above my head, and got off in a hurry. On my way to the taxi stand, I had this gut feeling that something wasn’t right. All of a sudden, I realized I‘d left my camera on the seat. By the time I rushed back, the train had already left. The result was that I lost it, my beloved camera.

I felt so sad, you know, for a second, I really wanted to stick my head into the oven. I couldn’t stop blaming myself for over a month. One of the most obvious consequences was definitely the monetary value. The camera was a state of the art SLR from Canon, I mean, a real pro one. It cost me a fortune. And having lost it meant I had to save for a really long time to get a decent replacement.
Besides, it was not just the monetary value of the camera I cared about, it was also the memories the camera stored. There were so many beautiful photos that the camera captured, like the one I took of the sunset on the mountain, and the one of the rope and chain bridge in the wind. What was worse, I hadn’t got time to transfer the photos of that trip to my computer yet. I lost everything.
This devastating experience told me a lesson – never leave important things unattended. I seriously hope I’ll never be this reckless again.
