This is hard since I study CS. It's a pretty individualistic setting where people usually study by watching videoclasses and doing lone projects. The study group is usually the clique you make on the first month of classes. Ever since my first two cliques dissolved as people dropped out I found myself pretty much stranded alone on academical matters.
I live in Brazil and the night is scary. Parks are dominated by the homeless and addicts. Gas stations are usually inhabited by conservative folk I'm far too queer to mingle with (this entire country but the southeast is basically a red state). No metros here and the bus station is also somewhat of a dangerous place at night.
On sports, school was already a nightmare. Always picked off last, didn't have reflexes, didn't even have the strength to throw the ball to score on basketball. Maybe martial arts. They're usually cool.
Thanks for your reply.
