My brother and I are planning our parents' anniversary party and he keeps saying yes to every idea I suggest even when I can tell he doesn't agree, and then later he'll mention concerns to our sister who tells me, and I don't know how to get him to just disagree with me directly so we can actually plan something good.
More people experience this than they realize.
The planning process is being undermined by one person's inability to express direct disagreement.
