Yup I had one family ask me if they could drop off early as mom had to start work early and dad was supposed to drop off but got stuck out if town in a snow storm so I said yes she could drop off at 6 instead of 6:45 and when I came out if my bedroom that morning at 5:20 to make my tea and get my kids lunches ready she was already in my basement... Had turned on all my lights and her kids was running laps around my basement and squealing at the top of his lungs ..... I went half way down the stairs and said "oh your early I'm not ready yet." Then I looked at her kid and said "shhh everyone is still sleeping" and I went back up did what i had to do and sat on the couch with my tea till 6. I posted a note that day that the door would now be locked and when the outside light was on then they were welcome to come in. This particular family is no longer with me ; )
