You've pretty much cut to the bone on this one. Expectations, think on it. When we expect something we are taking away some part of our s'es individual right to choose. Shouldn't they retain the right to choose how to behave towards us? Don't expectations give rise to resentments? As in: "I've done X and Y and now s/he tells me that they expect me to do A and B". At the same time we cannot expect our s'es to mind read.
I think that your technique is very spot on. By leaving the decision up to them we do not place expectations on them, rather we give them the information they need to make their own decisions without having to mindread.
Good stuff.
