last time my grandma oso like that, when my grandpa is still ard, i think grandma is treating my mum very badly. she can ask her to do all the house chores, eg cooking for 20-30 persons during cny without any help, just bcoz she said my mum is the first DIL, so this is her job! she still needs to wash all the dishes after cooking, very poor DIL i will say. actually, we are much more fortunate to be born in this era. grandma always think everyone will listen to her, but things changed after grandpa passed away. slowly, the two sons that she dotes a lot, also leave her, and even chase her out of the house! she is now staying with her daughter, but not the two sons/DILs that she loves and protects so much when they were young. and till now, my parents will still give her money as and when they gonna visit her.
sometimes, ppl just take it for granted. we will nvr know what happen the next second. only when things happened, then they will know the DIL that they always curse & swear is actually the one who cares her the most, or say who will be w them till the last day of their life! or if this day nvr happen, i will think... we will still doing the right thing by forgiving them, so that our kids/DILs will also treat us nicely in the future, just treat it as "积福" ba...
