Well,I do tend to ramble when I am nervous for some reason or othere, but I find that I tend to get along with guys more than girls...
Especially some of hte girls that I know, as sthey seem to want to do is hang around and complain about someone who's not there at that point in time, and then, go and recite everything that anyone else said to tehm later... I cant' handle that kind of decietfulness... guys mainly aren't like that. If they have a problem with you, they tell you, and I'm very like that!
Uni is much different to school for socialising, but I normally hang out with them watching TV, playing cards, drinking... just whatever!
As for a piece of advice, with my guy friends anyways, speak to them... Don't just hang around in a corner, trying to pretend for all your worth that your not there... just join in on the conversation! They might tell your that they think that your opinion is stuipd sometimes, but it's not meant as a personal insult, just that they disagree with you on that point...
Anyways, that's just how I see things!
