I have never understood the "I can't talk to my male friends" meme. As long as the vibe is right you can say anything. And nz men have a reputation for being emotional brick walls. (In a relationship I can be an emotional brick wall so I get it)

But when I catch up with a friend I havent seen in a while and we ask "how have you been" its a genuine question and sometimes the response is "not good man, ..." Its easier to share mental state concerns with friends than partners.
