Hey, relax !
After 30 years of study, I will say that
when I hear what may sound, to the uninitiated,
like a Chinaman and his wife having a vicious argument,
that I know, that they are most likely actually having
a pleasant conversation about the weather !
( She sounded like quite a well trained speaker of English.
A less proficient person will have you ROFGAF
( Rolling On Floor Giggling And Farting ). )
