-Sorry, Sir, this isn’t my mother’s language.  This is your mother’s language.  I don’t speak your mother’s language, I speak my mother’s language !

-LoL …

-Oh, you laugh ?!  I got you.  This is common language.  Your mother and my mother laugh the same.  Wait,  do you laugh at me ?  I will never know, because your mother and my mother do not speak the same.  But they laugh the same.  What a shame !  Not to be able to communicate each other.  It is your mother’s FAULT… hm…
