And one thing I've noticed, at least for myself-- when I am under the influence of hormones, I may be more weepy/irritable than I normally would be, but I'm never upset about something that wouldn't normally upset me. So I really don't appreciate the idea that it's okay to dismiss a woman's anger/sadness because "it's hormones." The hormones might be making me cry, but they're not making me sad.
My MIL used to say to my kids, "You're upset for nothing."
It made me angry. I would always say, "No, that's not true. They're upset because they're disappointed," or whatever -actual- reason they were upset.
Then I'd add, "Sweetheart, you are more upset than is appropriate for this level of disappointment. You've made your point about being upset, and now is the time to start calming yourself down and getting under control."
I also used to say to my kid, when she was going to school too tired, "Remember that you are very tired, and your emotions will overreact. So when you get upset or angry, you are probably upset or angry about something real. But your emotions will trick you into acting as if it's a bigger deal that it really is. You might be mad, but you aren't really as mad as you feel. That's the tired."
I felt it was a more valuable thing to teach them than to say, "You're upset over nothing," or "you don't have the right to be upset, or to express your upset-ness."
