Passing it on.
In recent years I have found myself passing personal safety advice to young ladies I meet at the grocery store, bank, etc. I was at my bank one time and got to talking with the teller, and I shared some tips she might consider applying in her life. Well, I ran into this lady at the bank again a couple months later and she said "that stuff you shared really works. I almost got robbed, but I remembered what you said, followed you tips, and everything turned out ok."
