I know I have mouthed off about this problem before. So please be patient.
Why the H-E-double toothpicks don't parents know their kids addresses and phone number?? Or at least have it written down for easy access??
You call the police asking for a welfare check or possible missing person report on your grown kid who you haven't talked to for months but can't tell that agency exactly where they live. If we're lucky the parent at least knows the name of the complex (which always has multiple addresses).
We check our records, run all sorts of searches and come up, usually, with 2-3 addresses for the person. So there goes the time and efforts of one to two officers going to the areas and knocking on doors, searching for the viable address.
Meanwhile the parent always has a perfectly good excuse for the reasons why they don't talk much with their kid and why they don't have the address or phone number of their kid handy and why they can't go to the last known location of their kid to try to knock on the door and speak to their kid.
Another thing to the parent who is calling for help:: don't call me when you're two sheets to the wind and want to whine and complain how the other parent is harassing you about the fact the mutually shared grown-ass kid isn't calling them.
