I agree with the idea that university students do a part time job.
Firstly, they can make friends with those who do the same part time job.
I think university students tend to be familiar with only their classmates, so it is
interesting for them to make friends with people who are in different positions through part time jobs and to talk with their friends.
Secondly, I like money.
Therefore, it is good for university students to do a part time job.
