I have my own problem, may be others too. I'm confused with the usage of 'Could'. I have the following problems.
Well, I could go with you if you really wanted me to.(I have seen this word written.)
Can't we write it following way:
Well, I could go with you if you really want me to.
and if we can or can't, What are differences between the two?
You could take the ferry if you wanted to, if that seemed like a good idea to you.(I have seen this word written)
Can't we write it as:
You could take the ferry if you want to, if that seems like a good idea to you.
Can we use 'Could' following way to speak about present continuous:
John could be the one who is stealing the money.
I have confusion about if writer is speaking about past or present or future. It would be nice if someone can/could explain this to me with a few examples.
