I will very willingly talk to and at my professors, especially at seminars of my interest. I will only speak to my classmates once I have confirmed that they have an interest in something that I have an interest in. But that is where it ends. Example:
As a graphic designer, we thrive on working as a community at school. When I transferred to a university, I was completely isolated. My sketches were SO small because I didn't want anyone to look at them, but I wanted their critiques. Yet, I was the silent storm in my class. I was very good at giving critiques because I was so technical, however, I did not like talking to my classmates about other subjects. So I simply didn't and couldn't talk to my classmates. It wasn't until during last semester, after over a year and a half,\ with my classmates that I began opening up to them -- out of necessity. And at that point, it was too late: we began working individually on our own things, and that companionship that I felt with them, even though it wasn't apparent, was gone, and I struggled. As a result of that struggle, I forced myself to open up to them so that it didn't seem that the only reason I was talking to them was for their critiques or knowledge of art. I went from being the dark horse to literally being the 'go-to' person -- for critiques, for 'emotional' issues [because I didn't pour myself emotionally into people's problems], for random research. I went from being a nothing to quite something...
My professors kept saying, "I didn't know you were this funny!"
My struggle is still getting out of my confines and making large sketches and writing large enough for other people to read my handwriting, and my professors, while they want me to get my masters because of my technique and my intelligence, all agree that my sketches, small hand-writing, and limited sociability are going to limit me exponentially, however, the results of things into my design are what stagger them.
Yeah, I definitely just didn't answer your question...
