Imagine you're thinking of moving to a different country, but it is actually a difficult decision, where not only you but other people will be affected, some of them negatively. Now consider all the people at work from whom you'd immediately accept an invitation to a lunch/coffee. Are all of those people "close enough" for you to disclose your intention and ask for advice? Those that aren't are approximately the "sociable acquaintances". Sociable acquaintances require almost no trust from each other, beyond believing that the other person is not psychotic, or a dangerous sociopath, or something of this sort.
