I let my sisters friends take her dog...

They showed up my house when she wasn't home yet and i said they could stay till she got home. After a while they said they were going to leave till she came back and they asked if they could take my sister's dog (a little shitzapoo) and I didn't think anything of it... so i let them take her dog... found out later in the night that they didn't return her till super late and had taken her to one of their houses to meet his dog, and they also let her drive... When i was getting ready for bed she was practically passed out on the couch... I think she had fun :)
