Abby's Little Mis-Adventure

So, yesterday the little 3 year old granddaughter, Kaya, of our neighbors came over to play with Abby. I wasn't feeling well after a little bit, so I went and layed down in my bedroom at the back of the house. I could hear the girls playing fine and I wasn't worried about them. Well, after a little while Lucas came home, he was upset about some girls who were teasing him on the bus, so I let him watch TV in the living room, and between that TV and the one I was watching in my bedroom, I didn't think about the fact that I couldn't hear the girls very well because Abby has never done anything bad.
Well, a little bit later the neighbors came back to get Kaya and I went upstairs to get the girls from Abby's closed bedroom door. They weren't there, but I wasn't worried, I just figured that they must have gone down to the unfinished basement to play, so I checked down there- no girls. I started to worry, mostly feeling bad that the neighbor was asking for their kid and I didn't know where they were. I searched the whole house, calling for them- nothing.
I heard the neighbors son's motorcycle start to drive around the neighborhood and I thought, well, she probably took her for a walk, sometimes Abby likes to go for walks around the block, but she knows that she isn't allowed to go alone, so I sent Lucas up one way and I went the other, we met party around the circle and still no sign of the girls anywhere.
Now, I really started to panic! I started to go to some of the neighbors houses that Abby had gone to to play before, but no one was home. We all started walking around the streets- I sent Lucas to check at the park. We still couldn't find them. Now the neighbor with the motorcycle had checked out entire neighborhood and couldn't find the girls. I started to cry... I didn't feel in my heart that something bad had happened, but intellectually I couldn't shut my brain up from thinking of how easily they could have been taken by someone... I also was feeling absolutely terrible that this happened to my neighbors little 3 year old on my watch...
We saw a couple of teenage boys on the street and they mentioned that they had seen the girls and told them to go home, but clearly the girls hadn't listened to them. Those boys started to help us look, running around looking for the girls. I ran into a few other neighbors to helped to start the search. There must have been over a dozen people looking for the girls by now.
Finally the guy on the motorcycle drove up the main road in our community and found the girls at the constructions site of the new school that is being built, it is probably a little less than half a mile from our house. I started running in that direction, the guy on the motorcycle gave me a ride and I was so relieved and mad when I saw Abby again. Motorcycle guy took Kaya home and I carried Abby yelling at her and making her cry right along with me as we walked back home.
Another friend who was out driving looking picked us up and gave us a ride home. Needless to say I was feeling so grateful for so many wonderful neighbors who were so willing to help out. I also grounded Abby for a week and took away her TV priviledges for a few days (this actually hurts me as much as her, but it is her favorite thing, so I had to do it!).
Now, I am thinking very strongly of putting a chain lock on the front door so that the kids cannot get out without me knowing about it! Needless to say I felt like the worst mother ever and I am sure that the neighbors won't let Kaya come over to play with Abby ever again!
