It's unfortunate if it came across as one-sided, but I tried to make a point that "noticing nuances" works for all sorts of relationships. In this case, yes, I royally screwed up my relationship with that girl ... but being selfish and ignorant to other's needs and desires goes way beyond just romantic relationships. So yes, I agree, "they" are certainly people, and this is a reminder to treat each other how you want to be treated.
