Kids love cell phones and almost all phones these days come with little cameras attached. Do you have a teenager with a cell phone? Want to know what they are doing? Do you have trust issues? Call the kid and tell her to take 4 fotos of what’s around her right then and email the fotos to you. That’s how you can tell what’s going on. Just telling the kids you might do that brings them up short.
And don’t buy into that old chestnut “you don’t trust me.” The answer is simple “trust but verify”.
