The "last seen" feature on WhatsApp is a window into someone's soul. You know they were online at 3:45 AM. You know they were online at 8:02 AM. You know they were online five minutes ago but haven't opened your chat from yesterday. The math is simple. The pain is complex. Nigerians have turned last seen into detective work. You track patterns. You notice they come online every morning at 7 AM but only reply to you at noon. You see they're online during work hours and wonder if they're actually working. You check during weekends to see if they're home or out. It's not healthy. It's not rational. But it's universal. The accessibility of information has made us all private investigators, and our relationships are the cases. Have you ever stalked someone's last seen? Be honest. And did you ever confront them about what you found?
