If you have family, work from home is great...sometimes. It depends on the people. Sometimes small children, or even adults, are better able to cope with you being occasionally gone, than with you being there, but don't bother them. You could end up either being continually interrupted, or else having to say some variant of "stay away from me" to a loved family member. Neither is a good situation.

Not to mention that some people, for financial reasons, must live in places far too small to spend their waking lives in along with their sleeping lives.
