People saying ``we should be nice to each other'' when what they mean is ``I want you to be ``nice'' to me'' i.e. put their whim in front of your plans, and tell them what they want to hear (and gloss over that, by manipulatively implying that you're wrong for not doing what they want, they're not being nice to you!)
The effect of seeing a strong ``want'' as a ``need'' probably links in to this.
This is a ``special needs'' situation, not something ot foce on society as a whole, letting your cravings over-ride others' need for personal space.
It's a pity there's no convention (of clothing, badges, or whatever) to clarify who wants space and who wants ``contact''/``affirmation''.
