Before parents arrive: we are impeccable, everything is beautifully in place.

During: we are delightful and complimentary, we serve drinks and food and never say ANYTHING bad about your children even if they fight all day and make us want to tear our hair out and we have to force our smiles every morning when you turn up.

Afterwards....

That's what you guys don't see! We break out the rest of the booze we were serving you and cart off all the food you didn't eat in ziplock bags. I think you can see some grabby hands in the photo I took, since it was hard to get a shot when teachers weren't attacking it.

We drink the rest of your wine, crack open all the beers that got neglected, and some of us even slip outside for a smoke. We laugh and joke and then we all trundle home with our goodies.
