alt Hacker Newsour family has had a special 'code word' we have had since the kids were in elementary school. If someone ever needed to pick up our kids from school (they never did) our kids were taught to ask for that word.
This is a good reminder that we should review that, since its been 10 years or so.
This. All of this is a solved problem. It's just not a thing that most families do and do regularly. Code word, insider info, etc. "Oh I am so sorry you got arrested Tommy. Before I wire the $, where did we go on vacation last year?'
