As far as I know from people around me, there is a sophomore who has only friends after 18 years old, but no good friends. Although I am excluded, there is still a long way to lick the dog, but think about it, he is right and quite in line with his personality.
Therefore, making friends varies from person to person. Some people are busy expanding their social circle, while others are alone. The emphasis is different.
Regarding whether college roommates can make friends, I think you can make friends if you recognize each other's personality and have a good impression on each other. Don't assign tasks to yourself and set rules for yourself, just like "I want to get along well with my roommates in college, get along with them and become good friends", which will put too much pressure on myself and remind myself to keep high emotional intelligence at all times, which will make me a little tired. There is no denying that emotional intelligence is very important in a long-term roommate relationship.
