Slighty off topic response, but made me think of this last night.
My Uncle married someone from Peru. I actually hadn't talked to her in several years and just spoke within the last few months back when she found out my dad passed away. I was shocked at her English - she's lived here 45+ years now. But she told my mom and I years ago "I understand Englesh fine, but when I no wanna talk, I no understand Engleesh" (at the time refering to not wanting to talk to my grandmother)
When I was listening to the attorney (in between squeals from my daughter) last night. I thought - she's being obtuse, and trying to sidestep - she absolutely understands what is going on.....
In my own, not so humble opinion, anyway.
You may be right about what she is doing. My suspicion is that she and Tito mumble whether they are speaking English, Dutch, Papiamentu, Spanish, etc. They both sound like they have a mouth full of marbles. It really isn't that they mispronounce words like someone who has seen the word written but never heard it pronounced; they mumble and drone.
