The reward from parenting is raising an awesome strong kind productive member of society that you could actually be proud of and create amazing memories with.
How your child feels towards you is a reflection of how you treat them. Children aren’t born hating their parents.
And before some suddenly victimized unthanked employees lament about their teenage children’s dirty rooms, maybe try to understand their perspective where they’re overwhelmed with assignments and grades while also being pressured to work and own property as early as possible, while being bullied by other teens for being unemployed and not a homeowner at 14 and dealing with fake friends and crap on top of all the usual teenage emotions and hormones and crap, on top of you antagonizing an overwhelmed human child for showing signs of being overwhelmed.
Loved children aren’t filthy and depressed enough for their living space to suffer. Buying iPads isn’t love.
