Could you give me some "Second-guess" sentence examples, please? HI, Could you please give me some "Second-guess" sentence examples? And I know what "second-guess yourself" means though, and I just read the story and here is an excerpt from the diet article in a magazine(U.S. English) I'm not sure about "second-guess" part in this case. --.((..Taking time to snap a picture made dieters "second-guess" choosing junk food. )) Thanks in advance!
