Loving a kid because they are cute, or good looking, or smart, or good in school, is easy.
Loving a kid unconditionally, is hard.
If there must be conditions for love, I think it's better to love them because they are good, kind to others, and try hard. No one can control our looks, or the talents that we are born with. On the other hand, it seems reasonable to hold us accountable for our efforts, and how we treat one another.
I have a feeling if more parents do that, the world will be a better place.
