Comments [1]: Accusative and Dative Pronouns in Spanish

Thanks for the great website.

A question, in the above example:

'¿Has dado el libro a Juan? sí, se lo he dado (le --> se)
Did you give the book to John? Yes, we gave it to him'

Should it not be 'Yes, I gave it to him'? I thought 'we gave' was 'hemos dado'?

Thanks again.
