1) Although I am a confident person, I am worried about myself being a non-drinker and how that will fit in with the generally perceived university culture.
2) Hate partying, again not sure how that will generally portray myself to be.
3) I avoid public toilets, generally OCDish, absolute nightmare would be sharing a toilet/kitchen with many people and ones that aren't particularly big on cleanliness.
In a way, the first two points are synonymous with making friends. It's dawned on me how incredibly boring I sound. I promise you, I am a bit of a joker.
