If you are ever in the situation where several girls under the age of ten want to have a slumber party at your house, just say "no."
Why, you ask?
Because at 2am one of the girls might "see" a stalker outside and wake up all of the other girls. Then, one of the girls might "see" the same stalker, but with a gun. Then, they might start calling all of their parents and telling them that there is a stalker outside who is trying to kill them. Then one of them might have their mother come pick them up. Then they might decide that just calling their parents isn't enough and they have to start calling everyone they know (grandparents, aunts, cousins) to tell them that there is a stalker outside trying to kill them. Some of these relatives will be called 10 or 15 times. The girls might then decide that none of them want to be in the house anymore and arrange for another girls parents to come pick them up. And ALL of this while you are sleeping and have no clue what is going on. Eventually the commotion will wake you up only to find that one girl is gone and the other girls are all packed up and about to leave. And the worst part of it all, is that if there really was a stalker with a gun, the girls were never even going to bother to wake you up and tell you about it!
