Interesting. I just assumed DS9's vocab was different simply because he reads so much. He's always had a unique way of saying things. But now that you mention it, perhaps he said he had to "adjust his eating habits" when he lost his tooth versus "change the way I chew my food" because the "ch" sound was one of the sounds he didn't have until after speech therapy.
Yes, that is exactly the kind of thing she would do! And she can't read so I couldn't blame that. I always thought it was because my husband and I like to tease the girls by phrasing requests or question in the most obscure way possible. (Which doesn't even phase them anymore but I love the look on the friend's faces.)
