Not exactly a uni experience, but I've had a similar one.
I started the Access to HE course in September, and this was something I'd planned for over a year. I just couldn't start when I wanted to because I didn't meet their age requirements and time out of education requirements.
I was looking forward to this fresh start, and meeting new people. Then one of my closest friends, who signed up to the course because her mum was nagging her to do so and she wanted her to stop, decided about a week before the introductory 'Preparation for Access to HE' course she was going to do it. I was a little pissed off xD
But even though we do similar subjects, we're only together for 2/6 subjects, and each subject only has one lesson a week. While there's only one or two people I'd call friends I met on the course, I speak to others regularly and get on well with them. And it's been nice having her there. I'm often more tired due to college in the week and work at weekends, so if I don't see her outside of college, it's nice seeing her in college and being able to talk; she is one of my closest friends, so I feel more comfortable around her than anyone else on the course.
