The first vowel was A. The best vowel is E. Just goes to show. Never trust the prototype.
Vowels are like televisions: the ones that get used the most are the ones that didn't come first. An A is like that old portable black and white TV you grew up with. It's good in a pinch if you've got to watch the game on a camping trip or something. But secretly, the whole time, you're hoping for an E.
