[color=green] Well what we mostly do is that we address them when we go home or when we eat ....I think its all in the family upbringing...if your parents stress to you on filial piety when you are young, you would learn to respect your elders and parents when you grow up...agree?
actions speak louder than words...things you do that makes them happy is important...respect and patience is 1 way too...buying them their favourite food, bring them out...BE with them...
[color=darkred]Agree with Xavier.....
