I do not have the habit to call my mil mum or fil Father.. cos I am not staying with them .. and have bad impression with them. Not in good terms too. So when I didn't called them Mother or Father, my hub say I got no manner. What can I do?

Yes time for both of u to exercise some manners! Auntie uncle - could it be he hasn't switch over his default mode yet. Regardless, pls just greet, practice courtesy and everyone will be happier. Like teachers in school, even if we didn't like them we still greet them huh? Parents are unchangeable blood relations - u can't pretend it does not exist
