Education should be about learning not socializing

[mjk45]

Having been on a large campus I found making friends and working with colleagues happened the same way as it did at primary and secondary schools day , some through general day today interaction others through shared interests. some by happenstance.
My advice join a club that you are truly interested in it might give you a basis for some socialising as well as being educational, let people into your interests and start noticing which people you find OK .
You do have to put something of your self out there and maybe shrink the personal shield by a few yards and don't be so defensive , that doesn't mean trying to fit in with every one and being every ones best friend.
