Friends are everywhere girl, you're in college, the social network should be big.

When you work, especially in a company you definitely will get to know more people, it's almost the same.

If you're talking about part-time job then of course la it's only temporary, you wouldn't be able to contact your colleague when you're not working there anymore. Unless you're very good in socializing and the working environment is nice.

That's because you don't go out and socialize. The fact that you're shy, probably, but I don't know much about you.
