I'm chinese...
my mom called me a "sick insensitive bastard, you don't deserve to be human" (in chinese translation)
I said "I know" then went to sleep!
but stuff like this happens a lot in chinese families... take it with a grain of salt! or treat it like a joke and reply to these comments with "I love you mommy" in a cute voice. that always gets them to shut up, turn around, walk out, and think about what they just said.
