I have indian and chinese friends and according to them its common to be insulted face on like that from distant family members and inlaws however for arabs from even villages don’t tell people comments like your nose is big/ you look fat no matter how secluded they live. Therefore arabs especially women aren’t used to being insulted face on; by distant family let alone inlaws therefore may appear to be proud by not accepting the apology; but in fact this is quiet normal to act like that with insults much less that what she recieved because this is a rare occurance and when it does occur it is seen as being very rude. Many times i have heard people divorce when a husband swears at his wife so name calling isn’t really tolerated by many arabs.
