I have a great female friend who spent part of her life working both in a preschool and as an executive assistant. She says the jobs are basically the same. The important things are:

You are severely grumpy, please have a snack immediately.

Please take your ball to timeout, no one wants to play with you right now.

Look, I brought snacks!

Everyone needs a potty break!

You have to share your toys to get other kids to play with you.

Nap time!
