It may seem difficult to build and maintain a friendship during collage, but it is not impossible. I personally met some of my best friends while in collage and we still interact to this date.
I was able to do accomplish this by being myself and not trying to impress anyone.
The best and real friend hips come when the individuals you meet accept you for who you really are.
My recommendation is to just be you, be open minded to others ideas and input and build trust within one another by always being their for each other.
