B is bad. D (first letter of my name, i can never say my name), anything pronounced with the letter E (for example the number 8 is kryptonite...nigh impossible. And what do you know, my phone number has an 8 in it !) W, is weird for me. I can manage to say it as a standalone, e.g "double-U", but difficult to say words that start with it. For example "water", or "west"...hard. Le sigh.
