Even better than I thought

MIT economist Jonathan Gruber emails me:

Greg -

I thought you would appreciate this. My daughter likes doing her homework in my office but she needs a flat surface on which to write. She perused all the textbooks in my office and decided she liked your macro book best as her writing surface. Now she won't use any other book and won't do her homework in my office if we can't find your book. So now you have another reason to recommend your macro text!
