It happened to me that I touched by accident the exhaust pipe of my motorbike when it was damn hot and got burnt.
Now, what would you say to questions like ‘What happened’? I always seem to carry over the pattern from Czech and look for a preposition such as ‘on’ or ‘by’ but it all sounds awful:
I got burnt ON/BY the exhaust pipe.
So I always end up resorting to either a long narrative or ‘It was the bike’...
