Parental “sacrifice” is just a myth. A child's wellbeing is actually a parent's responsibility and not a favour. Any sacrifice is yours to bear, not theirs to repay.
Raise them fully cognizant of your challenges but know that it's duty, not charity.
I really dislike bad manners. Why do grown adults find it hard to say please, thank you, & excuse me? You literally get taught all these as a child.
