Describe a time when you broke something that belonged to someone else

I'd like to talk about the time I broke my friend's laptop screen, about three years ago. My friend Rustam had lent it to me for the weekend, because mine was being repaired and I had an urgent assignment to finish. He was a bit reluctant, because it was quite new and he'd spent months saving up for it, but he trusted me.

On the Sunday night, I was working at my desk with the laptop beside me, a cup of tea in one hand and some papers in the other. When I stood up to get something from the shelf, my sleeve caught the edge of the screen, and the laptop slid off the desk. I watched it fall in what seemed like slow motion, and it hit the floor with a terrible noise. The screen was cracked across the middle.

For a few minutes, I just sat on the floor feeling sick. I considered not telling him, but I knew that was not an option, since I'd need to return it the next day. So I called him that night and told him exactly what had happened. Rustam was quiet for a moment, then said that he was disappointed, but that he appreciated my honesty.

I offered to pay for the repair, and over the next two months I did, which cost me most of my salary. I felt incredibly guilty. Fortunately, our friendship survived, but I learned to be much more careful with borrowed things, and I now keep drinks far away from any electronics.
