While this is true, knowing someone set up a fibre channel network on the weekend is hardly a reason to call that person an obsessive wretch.

I know a very smart woman who's a professor of English literature at a university, and I know for a fact that she goes home on weekends and reads Sue Grafton murder mysteries ("M for Murder" etc.). This doesn't indicate that she's obsessive or wretched or has no life, and I don't think "are you reading anything at the moment?" would be an inappropriate question for someone in her field. Certainly we wouldn't want to force her to read all the time, and certainly we wouldn't want to force her to read Finnegan's Wake on Saturday morning, but for someone who wants to study literature for a living liking literature is important, and realising you don't might cause an epiphany.
