...because there haven't been any. It's merely a small conversational vignette on the topic of hypothetical romantic misadventures.
background: a conversation that happened to touch on the most recent two people I've been involved with.
Other Person: So, you only date academics?
Me: No, no -- I only meet academics. (pause for thought) I suppose I'd be more likely to date non-academics if I ever went anywhere other than my office.
Seriously, the last relationship I was in only happened because the person kept stopping by my office. And put like that, it might look sad. But to me, it's actually kind of amusing: I'm probably only ever going to date again if a potential romantic partner is delivered to my door like a pizza that I didn't actually order.
