I live in the country and when I'm out and at night my doors are locked. In the morning I unlock my door at 645 which is when I open and not a minute before. My outside garage door is always unlocked (unless I'm Not home) and parents come in thru the garage and down the stairs into the daycare. I never used to lock the door and I never had a problem until one day a parent asked if I could do a really big favor and take her child at 6 instead of 645. So I agreed and I woke uP that morning at 530 and got dressed and brushed my teeth ect and came out to the kitchen to put on the kettle to make tea and I could hear her and her child in my basement at 540am ..... I went down stairs and she had turn on all my lights and was letting her kid run around my basement using his outside voice .... I was shocked and totally pissed and I said to her " oh your early I'm not ready" I went up stairs made my tea and sat on my couch till 6 ...... My door is locked from now on. I will never open early again for anybody. My families know that if the staircase light is on I'm open.
