voice;
Nobody is calling that part careless. But whereas others are quick to greet strangers - be it to make them feel welcome, or simply to inform them of the circumstances - it seems to be less so the case with disappearance.
Those who are close will care and keep track of those who disappear, right? But there's no organized method for this, you've told me. The "care" in a disappearance is isolated to those who have emotional investment.
