Below is a sentence I wrote. Not sure if the relative clause here is natural.
It's rude to call a girl with whom I had only one talk by her pet name.
I wonder if it will be better to use a verb here.
It's rude to call a girl with whom I talked only once by her pet name.
Not quite sure where only should be put in this sentence, so I came up with another version:
It's rude to call a girl with whom I only talked once by her pet name.
Which one sounds more natural to you? Besides, if you have any other alternatives, please don't hesitate to share them with me.
