Where are the parents?

So it is 5 am and I am awake.  Wide awake.  Why you might ask?  My neighbours went away and have a young man looking after the house.  Whether he is supposed to be in the house or not, I don't know, but he comes and goes.  For a couple of nights, we have woken in the wee hours to air horns, people having a great time in the back yard and the like.   It's great, especially when I have to work in the morning.  At 4 this morning, the air horns and the cajoling in the back yard started.  When I got up, there were some youths in the back yard having a great time.  Did I mention it was 4 in the morning?  The fun didn't stop there, while I was up, I heard one of the girls(?) say, "Oh so we're going to drive around now?"  I know the neighbours van has been parked for a couple of months, I'm not sure if there's insurance on it.  After more slamming of doors, lights going on and off, the driver decides to carefully pull out of the drive.  I was standing at the front window by this time, and I think they saw me, as they were back in about 10 mins.  Did I also mention that none of them looked old enough to drive?
They came back and there was some more air horn action in the house.  They must have gotten brave, as they took the van out again with much hoopla, and this time I called the cops.  (I am cranky enough in the morning at regular hours and now I knew I wasn't going to be going back to sleep.)  When I called, the dispatcher said to call back if the van came back.  It did and 3 members reported.  Of the 3 kids I saw for sure, only one was escorted from the house. 

Where are the parents?  These kids are out and about at 3, 4 and 5 o'clock in the morning.  Don't they realize that their kids are not at home, let alone in their beds?  I have heard parents complain about the jobs that teachers do in the classroom, but where is the foundation that they are supposed to be getting from home?

Did I do the right thing?  I don't know.  Talking to them directly would have gotten me no where, as it is, the young man in charge has little respect for our property as it is.  I think that youth need to understand that there are consequences for their actions and if they are put in a position of responsibility they need to step up and act appropriately.

It is going to be a very long day today....
