When is enough, enough

I have always had an open door policy..Anyone can come over at any time...if they want to share out table, go for it.  I always have enough food etc etc to go around.

Well....C1's 'girlfriend' seems to be taking advantage of this..or maybe it just annoys me cause she is a girl and they are 14?  UGHHH

Let me back up a bit.  First, I dont think you can say two 14yr old are 'dating'.  Its just a term they use.  I think they use it to scare the hell out of us while it really means nothing at all.  This 14 yr old does not have  a very good home life.  Not abusive but 0 supervision and caring, etc etc.  You know where I live, well, she lives down by the river and quite often shows up at my house after dark after walking by herself, never seems to have a curfew...often locked out cause they are not home...lost power for weeks when it was getting cold out...etc etc.

Great...just went downstairs, all the kids are down there, and found them SNUGGLYING in the big chair.  THEY KNOW THIS IS AGAINST THE RULES!

Now C1 is grounded for his grades, she knows this, yet keeps just stopping by.  I know she is walking...what am I supposed to do???

Do I tell her no and let her wander around in the cold and wet without even a winter jacket to keep her warm.  Let her walk the 1+ mile home in the dark alone?

GROWL!!!
Now hubby will come home and give me an earful...telling me I'm to soft...I let him get away with anything etc etc.  I'd like to see what he would do when she shows up at the door two seconds after he gets home, its raining and cold and dinner time...I'd like to see him turn her away...

BTW  this is the second time she has showed up TODAY....
