Christine, You did the right thing... no question about it.
You cannot take any risks nowadays. With SMS notification, there could be hundreds of people at that party within minutes - and there could be so much trouble. There could be alcohol/drugs and people spiking drinks.
Can you imagine how much trouble that girl will be in if the party gets out of control and the house is trashed while her parents are away???????? Obviously 15 year old girls don't think of the consequences. Part of me hopes that nothing happens, but part of me hopes that something little happens so that girl learns a big lesson and her parents are furious with her. Talking of her parents... did they leave a 15 year old alone at home while they are on holidays?? That's just stupid if they have!

Don't worry about Jess.... she will get over it.

Shaun is such a little monkey. The other night I found 5 bottles down the side of his cot (between the wall and the cot bumper). Then tonight I pulled the cot away from the wall and found SIX dummy's!!! Then tonight he was in his room playing, and when Yariv went in there, all his clothes were on the floor. He had upturned his toy box, stood on it, opened the wardrobe door and pulled out all the clothes he could reach!!! I think it will be any day now that he climbs out of his cot...
