Look, I'm not a father, I'm not even seeing anyone right now. I'm just a 20 year old college kid...
You are a father, so you know better than I, but aren't those kids supposed to be your pride and joy? Aren't they supposed to be the thing in this world that you love the most? Letting them do this to try and prove that this "danger" has been over hyped seems reckless.
Can you imagine what you would do if they went missing? The pain you would be in knowing that you weren't there to comfort or protect them.
My hometown, Spotsylvania VA, had
three young girls abducted. My father was a Deputy at the time and spent countless hours on the investigation. The parents were absolutely distraught. These girls were more than double your girls age and you claim that your girls can handle themselves. Spotsylvania is just outside of Fredericksburg, a DC and Richmond area suburb-- not a dangerous place per se.
Even here at college, one of my best most close friends in the whole world is a girl. And I refuse to let her or any of my other friends (girls) walk back to their dorm or car. Think, these are just my friends, those girls are your daughters-- my friends are College age, your girls are not even half of that. Letting go is one thing, 6 and 10 years old is most certainly, in my mind, NOT that time.
In the end, it is your decision, but I hope and pray that you will think long and hard before letting anything like this happen, I also pray that your daughters would be safe if you should decide to let them do this...
