They aren't carolers

Note to self: Next time you hear someone singing loudly outside as they approach your door, and then a loud confident knock, it's not the carolers. It's probably best to just pretend you're not home.
That is unless your children get so excited whenever they hear the doorbell ring and they run to the door and throw it open before I can tell them no (I always keep it locked for that reason, but sometimes I don't do the top latch right and they can still open it). I guess it's time to sit them down and teach them a little lesson on stranger danger.
You probably all know who I'm talking about. No, it's not the JW's. This isn't the first time they've been to my house either. I should have recognized the singing and loud obnoxious knock. But, it was too late. My children already had the door wide open and there are two girls standing there.
The conversation goes something like this:
Solicitor: "Hi my name is Robyn soandso and I'm with Urban Nation. Have you ever heard of us?"
Me: (holding a hungry baby in my arms and a toddler holding onto my pant leg). "Um, no."
Robyn: "We come from the 'projects' and we're just trying to earn so many points that will get us a job promotion. You see, we're trying to get away from the 'projects' and make it on our own. We're not out begging for money. We're trying to earn it. And what my I ask are your names?"
I tell her.
Robyn: Shaking my hand, "It's so nice to meet you. Now how do you think you can help us earn these points today, Miss?" (as she's handing me the folder with magazines in it). Does this ring a bell with any of you? Now where in here do they give you a chance to say 'no'?
Me: "I don't see any magazines in here that I would want."
Robyn: "Oh those aren't for you, honey. These are donated to places like women's shelters." Again, where in here do I get to say 'no'? Instead they lead me right where they wanted me to go, the check book, and now I'm $33 poorer. I'm such a sucker. Or, Ijust don't know how to say no. I guess I won't tell you about the Lifeline Industries that employs deaf and blind people to sell their products like expensive light bulbs over the phone. They're not asking for handouts either. They're just trying to work for a living.
