I changed jobs 5 years ago, and went from going to an office every day to working from home....I really like it now, and can't imagine going to an office every day, but for the first six months I really missed the social interaction. But I think that was because I wasn't busy at the new job, and could go all day without speaking to someone. Now I have lots of meetings. I learned how much I rely on non-verbal cues, I still missing talking to people face to face. 5 minutes on a white board solves alot of problems....
What I don't miss:
- the commute, especially in inclement weather, folks around here loose their minds
- the dress code (I am convinced I'm more productive in sweats!)
- the mess in the office kitchen, some people were pigs and didn't clean up after themselves
- the line up at the microwave (IT folks seem to bring their lunches!) I ate my lunch cold more than once because I didn't have time to wait before my next meeting
- the smells, I could tell when some people walked by just by the smell, and had to get off the elevator more than once because I couldn't hold my breath for the whole 12 floors
- the noise of some of the inane conversations that went on around me (although, it would have been good source if I'd known about with forum 5+ years ago)
