Gloss: SINCE(aah) ME BORN+GROW-UP(aah) THAT/\ ME TELL-OTHER++ NEVER(em)
English equivalent: I've never told this anyone else in my whole life.
The mouth morpheme "aah" along with the movement (slightly slow) in these two signs has a meaning that may be easily missed. This whole sentence has intonation (emphasis) that is conceptually equivalent to the English sentence.
