Hello, everyone! Which among the following sentences is natural and right? 1.He wouldn't talk about work, except to say that he was busy. 2.He wouldn't talk about work, except say that he was busy. 3.He wouldn't talk about work, except saying that he was busy. Although I'm not sure, considering what I have heard of what native speakers usually say, for me #3 is the least likely to be possible. But, #1 and #2 have the same weight for me. Which is right? Many thanks in advance!
