One of the frequently asked questions to me is this: "do you know one Mr/Mrs/Ms/Dr XYZ at Sun Microsystems?". Invariably, I don't seem to know the person mentioned
I tend to explain that Sun is a big company and it is not possible to know each and every engineer/manager/support staff and so on. And full time work-from-home does not help either - one gets even less chance to meet people
I've to wait till next JavaOne/Sun Tech Days or some other event to meet my friends.
