After joining this company, I never think of having some co-workers walking into my life.
Co-worker equals to "the partners that do the work together".
After the work is done, you are done.
Yes, I do share life with my co-workers but not too often. Only several of them may get a small picture of how I live and what I am.
Recently, I gradually start to think in another way.
Perhaps, it's not necessary to change the whole schema.
However, the bottleline should be reset and re-evaluated.
At least, to some extent, it's also not easy to make "real" friends.
On the other hand, I do ask myself. Why are you so cautious on this kind of interpersonal relationship?
Why you don't trust people like you used to be?
Or, you just value "privacy"?
