I don't want him to read my mind. If I am "upset" it is my
responsibility, if I want to share with him, to tell him WHY I am upset. He's human, how should he know why I'm upset? 20+ years of dealing with men on a day to day basis has taught me this.
I think this kind of thinking ("I'm upset and he should know
why.") gets a LOT of women in trouble, as they expect their partners to have knowledge that no human could possibly have.
If you're upset, talk about it in as shortly and clearly and simply as possible. Expecting men to have ESP is only asking for irrational things from a relationship. That's not how most mens minds work. They concentrate on what is in front on them and see most things as problems to be solved. They aren't great at subtexual or overtly emotional thinking as a rule, so if you want him to KNOW something, you have to SAY something.
TALK. But, with a man, be to the point, do it in as few words as possible and let him know you don't expect him to fix
it, you just need to share.
