How the Christ can anyone interpret "aw" as "ah"? xD
If something's cute, do you guys go "ahhhhhhh"?
Usually when I'm "aw"ing at something cute, I don't use my normal tone of voice. The "aw" is greatly exaggerated and you can distinguish it from "ah." If I were to say "yawn" in that same tone then it would sound like "yawn" as opposed to "yahn."
