***** NOT A TEACHER *****
(1) We were there. If you had looked, you would have seen us. ( perfect English)
(2) We were there. If you would have looked, you would have seen us. ( Some -- many? -- native speakers here in the United
States say this. I think that it is STILL not considered "good" English by most people. I respectfully suggest that you say No. 1.)
P.S. Some of the teachers here get rather upset if we students use only our names in the title of the thread. If you can think of
a more accurate thread title, I think that you will get faster and more responses. For example, maybe you could have entitled this
thread something like "The third conditional."
HAVE A NICE DAY!
