Do you have any comment about this conversation?
I need the same text if it is correct.
Tony: What happened to you, Alex?
Alex: I had a train accident.
Tony: I hope you get will soon.
Alex: I am much better now.
Alex: I had a train accident. Not likely, maybe he was in a train accident.
What about this,
I had a car accident.
That's fine if the speaker was driving the car at the time. If the speaker was a passenger, then "I was in a car accident".
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
