"Just Bartemius. Or Barty, I suppose. Not Elder, no." Never again. Made him feel sick, even hearing that word so close to his name. Barty pulled the book out of it's box carefully, then held it out for Aziraphale to see as he opened it for him. "It's a nice edition, don't you think? I love getting books that are special. When you are better, I will take you to my favourite bookstores."

Maybe that wasn't most children's idea of a great outing, but he had a feeling Aziraphale might agree with him.
