Quoting Jorge Llambías <jjllambias@gmail.com>:
leaving {e'e} outside of the imperative mood pattern is unfortunate.
{e'e} can of course be used for self-exhortation too, like all the rest.
OK, so ".e'e" isn't a feeling of being confident, it's a feeling that someone is capable (possibly yourself).
How about ".ei"? I had been thinking it's your own obligation, can it be someone else's? Or is that what ".e'i" means, that someone is "constrained"/obligated to do something?
mu'o mi'e la bret.
