I tried my darnedest to be a good DIL, but SHE was never satisfied. Some people are never satisfied - especially spoiled ones.
One of the most delightful compliments my DGD gave her mother came after a particularly bad time she had babysitting. 'Mama, thank you for not spoiling me.' My DD turned around and paid me the same compliment.
Amen. Can't ask for much more than that!
