I read some news about my friend being robbed on a local newspaper.
The newspaper was published a few weeks ago, but I read it two days ago.
I wanted to send my late regards to her, but I thought she would ask me how I knew it. I was thinking to write this:
"I saw you getting robbed on newspaper by chance"
But I don't want to use the phrase, by chance, because I think "by chance" relates to gambling and betting.
