I was pretty lucky because I was in halls with a group of 5 other girls and there was a mixed group in the halls across from us... And we just sort of became a ready made friendship group. It went without saying that we'd go on nights out together and go shopping together etc. I suppose those shared experiences cement a friendship, by a few weeks in we already had quite a close bond and had our own 'in jokes' . Things move a lot quicker when you're spending most of every day with people. We then went on to live together for the next 2 years. We sometimes regretted not trying to spread our search for new friends a little wider, but we obviously had friends from our course and built up a larger group of acquaintances by 3rd year.
