I have a home office and have worked alone for a long, long time. Mostly, I like it. Despite being a very social person (party! party! party! — only I won’t drink or do drugs, if you don’t mind), I really need my solitude, and a home office definitely provides that.
There are a few things one misses, though, when working alone, one of which is other people’s bon mots. Thankfully, some bloggers share well with others.
