You're assuming narcissism as the main cause, but it could easily be stuff like "that new weird zit that's just propped up that you can't quite self-examine without taking a picture of". Or tracking weight loss. Or anything really.

As for "leave them on the phone", again you seem to assume explicit intent, but it's more likely to be a bit like leaving your underwear on the floor for a few hours when not expecting guests because you can't be bothered to tidy up just yet.

Then one day a child in the neighbourhood goes missing, SWAT raids your house due to an anonymous tip (likely by the murderer themselves), the press spots your underwear, and next thing you know you're called "The Underwear Killer" in the press.
