All of them are like that? Seriously? How odd.
There must be people in neighbouring flats or something that go out late etc? Can't you befriend them? Or coursemates, ask them out for some drinks?
Its never to late to make friends! Try getting them to be more adventurous, like when they are in the room try playing some drinking games or something and then build up from there! Or you could drag them out, thats what I do with my friends when they are being boring! :P
There is only three flats on our floor, one is ours, the other is a couple and the third is a 50 year old man. We don't speak to each other. I just feel like everyone has already made their friendship groups and i'm going to end up with these bores for the next year (at least). Sorry if i'm sounding really harsh on them but it is really annoying when I want to go out and have fun and they don't.
Just because they don't want to do the same things you do does not make them boring.
You thinking that it does, however, makes you an ass.
Go out with people you meet on your course, your sports teams, your societies then?
It never fails to amaze me how some of you un-boring, fun-loving and uber-social people are seemingly either too lazy or too insecure to actively find new opportunities.
