Daycarewhisperer, was that a typo? You have a lot to hide?

Even though my doors are always locked I don't think any of us should have anything to hide and should be able to let a parent in the door at any moment throughout the day without problem. I have had that happen and find it rude of a parent to show up without a call first because I'm really busy, but there should NEVER be anything going on that a parent can't see or hear. I'm not perfect mind you, but nothing secret goes on here.
