Back to Basics?

Just moments ago a white van pulled up next to my curb, it said the name of a company on the side in black lettering constructed with what looked like black electrical tape. The van said it was Ohio (I'm in WI). My kids ran up to the side of the van, and as I watched from my living room window I almost had a heart failure. I dashed out the front door, freaking out...the guy was leaning out the window, talking to my kids! The sad part is...it was an ice cream truck. With the circus music blaring from the roof as is customary in an ice cream truck that travels the neighborhood selling yummy treats to little kids on the side of the road. Careful not to crash the happiness my kids felt I let them buy a treat. Paranoid still, I made the kids come in and put their treats in the freezer (told them it was because dinner was almost ready) until I can look at them closer. I'm giving myself some time to consider my next move. I want my kids to be able to trust people (although when it comes to the saftey of my kids I rarely do), but I also want them to know the dangers of people trying to hurt them. Many things are running through my head right now...what did he do to the treat, he knows where kids live, he knows how many and how old, he knows they like treats and are more than willing to come up to his van...however, he also knows, thanks to my paranoid mind that within seconds he'll also see mom hanging out on the front porch watching closely. So, I think I'll warn them of the dangers of strangers...again...and I'll check their treats in secret and try to get some sleep tonight while I worry if they are getting sick. Crazy mom, paranoid mom, yes....safe kids..hell yes.
