Agreed - it's personal.

I'll add that I enjoy moving people from 'sitting next to me' to 'known', and given that there are not that many people sitting next to me, and I have a fixed office plan (always the same people next to me), it works for me. I would not enjoy going to the office if I wasn't around the same people/there wasn't at least a bit of stability. We didn't mention this : if your company has a flexible floor plan, indeed, then you won't know your co-workers!

It probably depends on the kind of job you do as well : a significant portion of my job is spent talking to people anyway, and I'd rather make it as pleasant as possible. If it means getting to know people, then I'm quite happy to do so.
