Someone tries to say what I do not want to hear and what is not appropriate, which sentence is natural to you?<br/><br/>This is not a good <b>time</b> to talk about it. VS. This is not a good <b>timing</b> to talk about it. <br/><br/>I think the second is correct but I also have heard the first one used. What do you think? Thank you so much as always and have a good day.
