I was the only person in the SF office for an eBay team in Portland. The other CA people didn't bother coming into the office.
That was the loneliest job I've ever had. I was alone in a bank of desks, basically every day. The nearest group of people had nothing to do with my team.
I worked from home on that job for weeks at a time and no one said anything. The funny thing was that when I was at the office, anytime I needed to speak w/ anyone, I had to leave my desk and find a quiet place. It was inane. The only upside was the free Diet Dr. Pepper.
So even when I went in, I never dealt with team members.
