So today is International Women's Day. I suggest everyone, women included, think on the women we know in our lives and let them know how we feel about them. Try and think of some particular aspect about their being that is particularly feminine, and let them know how much you respect and are grateful for that part of them.
It would be best if such reflections did not center around her physical nature, but rather focus on the mental, spiritual, or emotional things which show forth her unique womanliness. Such reflections may be difficult, especially having grown up in such a world where we are constantly bombarded with arguments as to how there are no differences between women and men, save from the difference in genitalia, and even then many are trying to say that such differences are unimportant as well. If one is stuck on the physical, think about a better way of saying it, that shows respect and remembers the dignity of the woman such as: "I like watching you take care of someone; there is a softness and tenderness in the manner that you use that really makes you beautiful" rather than "Your body is so hot, I like how attracted to you I get". Or something to that effect; it sounded better in my head.
Thank her for the different point of view that she brings to the table. Let her know how much you admire her ability to emotionally connect with others. Commend her for facing whatever trials she has faced with whatever strengths and virtues she has. Thank her for her life, and let her know how glad and blessed you are to be a part of it.
