> It's interesting to think that "quality time" which in this context simply means "2 hours per day together" should be enough. This is not how humans evolved. Just pointing out that this is an assumption and should not be taken as fact. If this is a fact and it's obvious, I would encourage you to write down in detail the reasoning. The best way to improve your thinking is to do this. Usually writing to explain encourages you to study your own presumptions. Digging into your presumptions usually leads to realizing that your world view does not take into account enough detail and forces you to seek out more detail. This detail usually changes your world view, which then changes how you argue things.
