This is so funny. We have an almost reverse situation in my family. My husbands been in the states for years and speaks very good English. He understands everything I say... screaming... yelling.... few curse words. L o L, but when he gets angry and starts running his chops.... no one can understand a word he is saying... with the exception of one bad word, and he is speaking English. He is just speaking too fast. The kids and I just shake our heads.... we laugh about it all the time., happens all the time in the car, he is a very impatient driver.
