I have difficulty with the voice inflections, but I do manage an "AAAAAAAAAAAAOOOOOUUUUUUUUUUUU" every once in a while. Sometimes I bite my lower lip too.
Funny this morning I saw my reflection in a jar, all distorted and stuff and I thought to myself, "self. Imagine if someone, somewhere else were holding just such a jar and perhaps seeing their own reflection, all distorted and stuff, and possibly yellow in colour, and somehow the two thoughts joined to form a single tone which would emit from each of the two half-filled jars." No message could have been any clearer. Mayan gold indeed!
