I am an international student and I have got my first job as an intern at a company in Canada. I sometimes think that I am not good at communication and making friends. I have very little friends at school and zero friends in the workplace. All the stuff that I am talking to my colleagues is work-related and we communicate through a particular email that the company has provided. If I or someone changes his/her job then there is no chance that I can get in touch and friendship ends. I am an introvert but like to socialize and sometimes at lunchtime, I feel awkward to bring my lunch and eat it with my colleagues and have a chat. When I have a chat the talking ends quickly. My company has a kitchen where most of the people eat (there are huge tables, micros, fridge, etc).
I have social media but not active there. Do people usually do not make friends at work? or I am not a fun person that lacks having friends? I think that might be something about the culture of the country.
Edited: I am trying to be friendly with my colleagues and participate in social activities. They know me, but not really any friendship.
