It is creepy. Last time this happened the man even told me I could not come pick her up because he was afraid what "might" happen to her at home. I told him he could either give me his street address, or I would just start knocking on his neighbors doors until I tracked him down (at 1:30 am). I'd like to know what he would do if someone tried to pull this crap with his own daughter.
Shadow - you have to be kidding here. How old is your daughter? Why is this man taking your daughter to his house - does he have a same-age daughter that your daughter is visiting with? How old is this guy?
What does he think might happen to your daughter in her own home as a result of her going to his house? That she would be punished for sneaking out and going to his house? What does that have to do with you picking her up at his house? She is ultimately going to come home anyway.
Creepy doesn't begin to describe this one. How old is your daughter, once again?
