tl;dr synopsis: All IMO - Stereotypes, deal with it. In my experience the article holds true. Guys problem solve with logic, girls comfort and pity with emotion.
The long version:
I dunno how people are that upset about this being sexist. These sorts of generally common actions have been around and associated like this for years for a reason. "Generally" is the word here, not absolute fact to everyone. Just because some people are different, unless it's the solid majority, it won't change quite right away. That goes with any sort of "stereotype."
White, Asian, Hispanic, etc. people play b-ball, yeah duh. But when we see mostly blacks on the court while watching TV, movies, or looking downtown blacktops (pun not intended,) then you'll see it's generally Black dudes playing. That's just how majority and generalizations work, and I'd say "Deal with it." Make your own choices and opinions without getting salty about it.
Ahem, anyway. I personally think it's much harder for guys to share their thoughts just in general. While drinking with my buds, we noticed one of the guys smoking a lot, despite him supposedly quitting. We hit him up, asking if anything is wrong. The with three of us, we have no problem confiding in each other, but this guy spent about 10 minutes in silent just trying to figure out what he wanted to say... and actually never came to much more than "it's this girl..." Eventually, we just distracted from the subject, but I believe more for his sake than anything.
I'm easy to share my emotions, as a guy, but it has to be with someone who I feel will be willing enough to seriously listen and concern themselves with it. One guy posted on this thread that girls just go "Aww..." But yeah, I don't wanna be Aww'd 98% of the time, I'd feel pathetic and my man-like pride feels kind of crushed ;P (I know it's a stupid way to put it, but it's totally how I feel, hahaha.) <-- Leads into another example: When guys, in my experience want to explain stuff, it's cut and dry and simple. Not a lot of 'feeling' goes into it.
Lastly, guys for millions of years have been "problem-solvers" in history. So, in my experiences, when girls wanna talk about problems to a guy, the guy will often go into figuring out answers to her predicament when the gal might just want an ear to talk to. And vice versa, as kinda said above. Girls will just listen, but the guy will want something more solid than pity or comfort.
Also, I lose contact with a lot more female friends than male friends on negative, or even general, basis. The female-backstab theory hold water in my head.
