The hijacking thing reminds me of a girl I worked with years and years ago.
She was from PR. She learned her English in high school and college. Her spoken English was fluent! However, she had a bad tendency to take everything literally! And I mean LITERALLY!
She would overhear somebody say something like "fuck you", "fuck that", "mother fucker" etc and she would actually think somebody wanted to fuck the other person. I am not kidding. Seriously laughable on any level!
Took her about 6 months or so to catch on to American culture!
