Be grateful of what you have, even though it is not the best, at
least it is something.
you know the children in Africa.... they four five years old
have to start to find food for themselves already. some of them by
ten years old already a parent, by twenty years old already a
grandparent already.
meanwhile, we are almost twenty and still living on our parents.
think about how lucky we are. treasure what we have.
study hard.
don't need worry about cannot re-pay parents. next time with a
diploma you can get a job that pays around 2-3k. with degree even
higher. surely you can re-pay parents.
there's this saying in Chinese that goes "sky down father mother
heart", which means every mother and father in the world love their
children.
appreciate what you have.
if you do not like the smell of cigarettes, tell them to quit
smoking. anyway, it's also for their own good. I'm sure they will
understand and accommodate.
