Doing things on weekends

In my experience, the extroverts and/or the ones that always have to "moving" are more likely to want to make plans and go out. I am an introvert and usually come home from work exhausted, so I have no desire to go do things with other people.

My work is kinda alone at my pc so ya, still studying in university but i always give myself extra work so i can learn new things

Makes sense with your work. I work with people that need CONSTANT attention, so I welcome the peace and quiet at home.
