Hey The particle,
(also thanks for the tag Reality Check!)
I'd second what Reality Check has said. It doesn't make things impossible with regards to socialising, but it does make things a bit more difficult. You'll miss out on making friends with people you live with in halls or around campus. BUT, you will still have the opportunity to have friends through classes and societies.
I traveled/travel in from home and face a similar commute time to yourself. I made friends on my course and we went out for drinks after class, went to the forum clubbing a few times and generally had good fun.I wont lie and say that having the 1 hour travel time wasn't a hindrance. On occasion, I missed out on some social activities, as I couldn't get home easily late at night. But, I made arrangements in advance for other events and found I could take part in them.
The one advantage you'll likely have over me is you'll have a decent late night train link to where you live. So if you want to stay out later, you can. There is also the possibility you'll make friends you can stay over with like I did.Also, if you drive that gives you some flexibility in arranging things.
Again, being brutally honest as I'd rather give you the facts. Many of the clubs and societies have activities that gravitate towards the evenings. For me, this proved to be a big pain due to the mode of transport I had to use! But again, this didn't make things impossible with some pre-planning.
The long/short of it is. You can and will make friends regardless. But, you'll be missing out on a part of the University life experience.
All the best,
David
