a bit upsetting

Every few months we hire Kerrie to babysit our kids so we can get out of the house together for a few hours. Our kids love her, and she loves them. We'd hire her every week if she didn't prefer to be paid with money. Last night before we were even out of the door she was asking the kids if they wanted to take a trip to outer space and visit the moon. From Joshua's report this morning, it sounds like it was quite a bumpy ride, but they were safe in their space shuttle with their space suits on. I was thrilled to hear the report from last night until I went up to get Garty out of his crib. I walked in his room expecting to hear the usual joyous, "Mommy!!" Instead, he looked up and asked, "Where's Kerrie?"
