I don't exclusively socialize and I certainly don't have a rule about it. It could just be a coincidence that most of my Adelaide friends are PhD students. I guess they've been at university for so long that they're cynical and jaded about academia, and life in general. I like that.
Anyone who's cynical about academia wouldn't go and get a PhD... I don't trust someone who can be in academia for that damn long.
Modesty Sadie, you're not going to get friends here or turn your red ball green until you show us more sexy pics.
I find myself to be more intelligent than most of the people I come into contact with on a day to day basis, which is why I hang out here. I need some stimulation from people who aren't idiots.
