It's very common on here to see a mother who is worried because some POS called CPS on her. Everytime, a bunch of moms jump in with "You don't have to let them in! Stand your ground!"
I don't get it. If you didn't do what they're accusing you of, and you have nothing to hide, why not just let them in. Talk to them a bit, answer their questions. Why is that so hard? Legal rights aside, it does look bad when you refuse to let them in. I just can't for the life of me understand why you would fight them in the first place.
