In the event tragedy strikes and your significant other goes missing, you may be expected to know their location or their anticipated whereabouts. This is a recurring scenario that plays out in police dramas on television and with real-life law enforcement as well - girlfriend disappears, first suspect is the boyfriend (if she has one). After all, you may even be listed as the emergency contact when your partner fills out their job application or medical forms. If you do inquire about a person's location on a day-to-day basis, they may become annoyed. If they don't choose to divulge their whereabouts, it could be construed as being secretive. People do value their privacy to some extent. It's difficult to imagine that someone enjoys being spied on, which may be the conclusion they arrive at if you're always asking about their movements. Someone may not go so far as to ask for your schedule in intricate detail, but if they know where you are often enough, they may know your routine, which could be vexing if things end between you two. Modern technology only enhances someone's ability to track you, especially if you're a regular on social media.
