Sorry to hear about the snake.
This might be off topic but I would be careful about letting children into your home without their parents knowing. I have had neighborhood kids want to see my collection and really want to watch feedings. I tell them they most certainly can as long as they bring their parents. As long as their parents know where their children are and feel comfortable with their kids being in my home then I'm totally fine with it. Once their parents get to know me and they are okay with the kids coming over by themselves I readily welcome it.
As a parent, if my kid came home and told me he was in a house with a stranger for any reason I would be extremely upset regardless of the "stranger's" intentions. My kid shouldn't be talking to strangers. In this day and age you just never know who is out there.
I'm not saying you are one of the bad ones, just saying until a parent meets you how do they know?
