LOL, you are right about the pronunciation of ISBN – it is the letters. You had me wondering there for a moment so just had my daughter check on howjsay.com 
Carrie,
I have absolutely no medical credentials so please pardon my armchair observation: but have you ever heard of Central Auditory Processing Disorder? The way you describe your phone call and that this sort of thing happens often made me think of it. I never heard of it ’till recently when a neighbor of mine told me about his daughter’s diagnosis. It’s essentially a problem with processing auditory information despite good hearing ability. Apparently it is also a another one of those conditions that can be co-morbid with ADD.
Anyway, just thought I’d mention it…
