The example I gave in my comment below is a different one but this is what I was trying to do actually. I was writing down this narrative that happened many years ago, like 10 years or so. I am saying about a particular day from 10 years back.
I wrote like this :
When I was a kid, I had many toys, but the toy train was my favourite. That year too I demanded another toy train for my birthday present as few days back the previous toy train had got broken. So my father bought this new one. I was very happy. But on this very fateful day, I broke the new one too.
This is where I am getting confused. I want to say that the toy was broken accidentally just few days before that fateful day. I didn't break it intentionally or consciously.
I feel like if I use 'The toy was broken', then the reader would think that somebody broke the toy because of some reason, which is not the case.
Same I feel with 'The toy had been broken'
It sounds odd to me if I say 'The toy got broken' or 'The toy had got broken'
So I am really confused about what to use here. Hope I explained properly this time.
