All I have to say to all of you is:

*in Godfather voice*
"You gotta respect your family, because without your family you're nothing"


I mean this both ways, parents and kids should both respect each other and be close to each other.
Butters' mom is definitely making a mistake, one never knows when one may need help, and usually the family are the first people one can count on, unless one fucks up one's relationship with their family.
