I don't find being a fan of architecture to be strange. Rather I find it strange that someone would be walking around and photographing a house on private property, especially one housing ~25 young females.

If someone was walking around my house photographing it, you can be damn sure I'd be uneasy about it. Likewise if there were people walking around and photographing a house of a chapter I advise.... you can guarantee I would be reporting it to campus police/ security asap.
