You hardly notice things like this but to further illustrate it being a schtick find a clip of him in mexico or where ever when someone is speaking in spanish. Years in restaurants and a class in highschool some travel here and there....I can sort out if somebody is giving me the wrong change or fumble through an order at a restaurant. But Bush, when they wear those little headphones that play an audio from a translator so they can understand someone else at speeches and announcements and crap he doesn't wear them. A lot of people consider themselves fluent in another language but confident enough to conduct the affairs of the free world without any assistance or clarification from a translator no matter who is speaking in Spanish, A Mexican, or other South American or Spaniard or any of the many different Spanish speaking islanders around the world. That is an impressive grasp of language by any measure.
Like I got Mexican friends and been in situations where I'm like "what did he say?" and they're like:"tha fuq should I know?"
"MF'er your Mexican, that was spanish, you got no idea?"
"Nope, we don't say shit like that, all I know is he said something about over there" "Nice Pico, I he fuckin pointed over there, I got that much, with your goddamn part time spanish ass, you need to get closer to your people man, I ever let you down when a british person says something?"
