Two scenarios:
Australian parents:
Kid A: Mum, if I do crap in maths, it'll drag my UAI down really bad.
Parent A: Alright sure, go ahead and drop it
Ethnic parents:
Kid B:
Mum if I do crap in maths, it'll drag my UAI down really bad.
Parent B (accent and ethnic language): DROP MATHS? WHAT IS WRONG WITH YOU! I AM A MATHS TEACHER I CAN HELP! YOU STUPID GIRL! GO STUDY OR DROP SCHOOL AND WORK AT MCDONALDS. YOUR A SHAME TO THE [insert surname here] FAMILY!
Even though I have ethnic parents, they'd never say that. The above was exaggerated, and don't take it as offensive lol. In summary, if you have ethnic parents, then bad luck
And lol @ ratcher's post about Russel Peters.
