I was talking with a co-worker the other day when I noticed her nipples had gotten hard (very visable even through her thick sweater.) Considering the fact that the converstaion was completly profesional and work related and it was not cold in the room I wondered why this happened. Can a womans nipples get hard for no reason?
Jack Dean Tyler had been power-sucking and pressing her nipples in.

The conversation may have been work related, but her thoughts about you were all pleasure… You lucky dog, you. 
Yes, mine get hard for no reason sometimes.
I should know better than to open these threads at work…
A breeze, her sweater shifted - whatever. Mine get hard when I walk briskly down a warm corridor, or if I brush against something. If it’s slightly chilly in a room - forget it. So, to answer your question, who knows? What, are you the breasteses police?
If it was a completely professional conversation why were you looking at her nipples?
Corporate America has taught me that when in conversation with a woman at work my line of vision should never descend below the her forehead.

EXACTLY! I used to work in an office in which 149 out of 160 employees were women. I was asked why the younger (3 of us under 30 years old) never complimented women or said they looked nice or smelled nice or exchanged any pleasantries. I explained that how any sort of comment could be construed as an ‘unwelcome advance’ and that a ‘repeated pattern’ merely means doing something more than once. Put the two together and you end up with the following scenario: I tell a woman she is wearing a nice sweater, on two separate occasions, meaning only that I like her sweater and it makes her look nice – both, harmless compliments. In today’s litigious society what I have really done is laid down a repeated pattern of unwelcome advances against a woman in my workplace. The effect is the same as yelling the ‘N’ word at a corporate function. I have ‘violated’ someone’s rights and my career is wrecked.
So ladies – if you aren’t getting compliments please don’t think all men are jerks, some of us are just paranoid.

I agree with Opengrave. I’m afraid to say anything even resembling a compliment for fear of being labeled an overly agressive babe hound. BTW obfusciatrist, I honostly was thinking of nothing but the additional work this female co-worker was heaping on me. The last thing I was thinking about were her nipples. It was just so obvious and happened to her so suddenly I wondered what caused it. I actually felt embarrassed for her, she spent the last five minutes of our conversation with her arms crossed over her chest.
Mine are always randomly popping up, some of the time in lopsided fashion. It’s craziness.
They have a mind of their own. 
Why are there more nipples then there used to be? Are bras thinner? Are we noticing them more, because we’ve told that we’re not supposed to? And its not just in the real world. Watch any tv show (well, ok not the Beltway Boys) and you see women practically “wearing” their nipples like accesories.
I think its a secret left wing conspiracy to get men to walk around with their eyes glued to ground, mumblin’ “Nipples, nipples, Don’t look at the nipples”
I think you notice them more because you’ve been told it’s a bad thing. Besides, everything’s gotten more sexual in the last couple decades or so.

Naw, it’s the clothes.
When I was in H.S. and college, girls wore humongous sweaters and sweatshirts and button-down shirts and great big baggy t-shirts. sweeping generalization alert Nobody would in a million years have thought of wearing a shirt that fit snugly around the body.
Now a lot of women are wearing really tight shirts all the time, so any nipping is a lot more obvious.
And they do have minds of their own. Too bad they so often disagree.

I was out shopping the other day with some girlfriends, and noticed that the mannequins in the store had very prominent nipples. I also noticed that they looked more like a C-cup than the former A or B cup. But what had me screaming “False Advertising” was that the C-cup was wearing some little halter thingy and had perky point-up nipples. I therefore concluded that the mannequins had implants. These D-cups weren’t exactly perky even when I was 17.

I vote for the “thinner bra theory”. In the 60’s/70’s (and I think the '80’s, nipples weren’t there. They certainly are/were in the 1990’s.
Not that I’m complaining
When I put a on shirt to go to work in the morning, my nipples usually, um, perk up. Now I’m happy to go to work, but not that happy. I think it’s a clothing-shift thing going on, too. And sometimes they do act up on their own. It can be disconcerting, to say the least.
There is definitely a nipple fad on the rise. You can buy fake nipples if you want that “hard” look all the time.
