Please look at the following
This is the best performance I have ever seen. This means I have never seen a performance which was better than this, so this is the best. Am I right?
Similarly, when we say
This is the best performance I ever saw. I think this means the same as above. Am I right? If not, then please tell me what the difference is
But, when we say
This is the best performance I will ever see. This sentence confuses me really.I don't understand what this means. Can anyone please explain to me what it means?
