The e-mail thing is controlled on the comment leavers end. If they want their comment to come through with an e-mail, they need to go into their profile set-up and check the Show My E-mail Address box. I have mine checked, so my e-mail should come through with this comment. :) My only gripe with Blogger is this e-mail thing. I wish it required all comments to leave an e-mail adress, like all other blog platforms do!
I love your story, what a wise mother you have.
