Hmmm.....
Before I get into this, I have to put out there that if you are reading this wifey, then I'm only generalizing and not talking about us. Really. Seriously. I love you.
Anyway, let's see..
This is in no particular order, is just off the top of my head, is probabl;y a bad list, and I am only generalizing here. (ie. not all men react this way). Also, obviously not all women do these things.:
1) Don't assume a man is psychic. While many men are very good at reading the feelings of women, many more are not. We men can not just "know" what you are thinking. The classic exchange that follows goes to this point.
man: "Honey, are you mad at me?"
woman: "Yes."
man: "I'm sorry. What did I do?"
woman: "You know, and if you don't I'm not going to tell you." (In other words, read my mind)
2) Not realizing that many men are not as able or willing as you to share deep feelings. Especially feelings pertaining to some failure on our part. Our egos are enormously fragile on many subjects. And, it isn't that we don't have feelings, but we are generaly conditioned by society to supress the expression of those feelings. Who hasn't heard the expression that, "Real men don't cry." I'm not saying I agree with that sentiment, but that is the reality of society (in the US at least).
3) As a counter-point to the above, sometimes we really don't have any feelings on a particular subject. Few things are more aggravating than to have a woman keep asking over, and over, and over what/how we feel about a certain (insert whatever here....meal, paint color, movie, etc.), when we really, really, really, honestly don't give a flying f@#$ in a rolling donut about it. I guess you ladies have to be mind readers to sometimes. No, seriously though. If you want his opinion on something (again, insert whatever trivial thing here, paint color, where to eat, etc.) and he says "I don't care.", then leave it at that He probably means it.
4) Assuming he knows how to be romantic. We want you to be happy, and (most) men will gladly do things that you consider romantic, but we aren't really rasied to know what those things are. Also, it varies woman to woman. If you want flower petals strewn all over the bed because you think that's cool, ya gotta let us know that. Some of these things don't occur to us.
5) Some men need more personal or "hang out with the guys" time than others. This doesn't mean they love you any less. It just means that to keep their relationship "batteries" charged, they have to hang out with their buds and "relax" the standards of conduct a little. I don't mean the moral standards, I'm talking about relaxing the social standards. To put it bluntly, sometimes a guy just wants to hang out with people who won't look at him funny if he farts in there presence.
It took me forever to type this, so I'm not sure what others posts are gonna hit the board before I submit this. Probably posts with a great deal more insight, but these were the things that came to mind first.
