If you have children and talk to them about danger (which you should), tell them that if someone is ever attempting to take them they should yell “you’re not my mom/dad!” That way, passers-by know it’s not just a kid having a tantrum
My mom taught me this along with having a password if one of her co-workers ever had to pick me up for an emergency or whatever. Once my grandpa came to get me and it wasn’t planned, I asked him the password and he didn’t know what I was talking about. I wouldn’t go with him for 20 minutes until he called my dad and got the password.
Very true for "basic" life lessons, things that don't change very much over time. It's not a generation thing, just a matter of people having lived long enough to gain a lot of experience in various topics.
BUT an absolute disaster, when it comes to things that change over time. The faster and more fundamental things change, the worse would be any advice from people getting their experience before the changed.
So, basically: Learn to differ what topics you can get really helpful advice from older people, and what things you'd better not ask them.
