I have a mom who works from home. She drops the kids off in her sweats and slippers and picks them up in different sweats and slippers. The odd time she comes dressed as if she came from a meeting. But she always has stories about the great deal she got at the store she went to that day, or the great sale at the grocery store... or the new hair colour she showed up with at drop off. It certainly makes you feel taken advantage of. She's usually on time, but she certainly pushes the limits some days. So, since she doesn't have a lot of concern for my time, I find that I don't have a lot of concern for hers. I don't hesitate about closing early if my other kids are being picked up early, or taking a day off for an appointment ect.
