Query: Good book, disappointing person

I purchased 2 Lemony Snicket books for my son and we went to an author appearance at a local bookstore. My son and the other kids fully expected to have an intelligent dialog with the author and come away with a signed book or two.I can forgive the author's eccentric style, even though I suspect he is trying to achieve a place in show business, not children's literature. Not one serious word was exchanged with the kids who were anxious to learn about writing. It was all ego and performance.I cannot, however, forgive him for not signing the books our kids presented. He stamped them like a common notary public and didn't actually sign them.Forgive me if I am naive, but I am used to authors signing the books we purchase.
