What broke?

 I start work early. The house is dark when I clamber down the steps to our home-office. I put on a little light in the kitchen, get my glass of hot water and coffee and I am set for the next 1.5 hour-ish before the kids wake up. 

A few days back, I woke up and went into the kitchen. There were a few vessels which were next to the sink, left for drying. As the kettle boiled the water, I thought it would be a good idea to keep the dried vessels inside the cupboards. I went about doing it. I have a glass cutting board. As I was going to keep it away it fell down. With a big crash! I was devastated and my first thought was Gosh! Now all the cleaning of the glass! I put on the bigger light of the kitchen. I picked up the cutting board from the floor. It did not have a scratch. But I was sure I heard a big crash sound, the resouding sound of glass breaking. So what broke?

I anyways picked up the cutting board. I managed a side ways glance. And I saw the door of the washing machine broken. Pic for proof. 

How did the cutting board manage to make a sideways kick to the washing machine (which is just under the kitchen work place) is beyond me. How did it manage to survive without a scratch is also beyond me.

I worried about the replacement and the response of K! But! Thankfully K was more intrigued by the quirk of the incident to be angry :D Some laws of physics are beyond us mere software professionals :D
