And it was all for naught

Today was Bethany's first day riding the bus. I've been worrying about it for weeks. I worried that she'd be scared going by herself, that she'd be overwhelmed when she got to the school and not know where to go, etc. etc. I tried to prepare her by telling her that she'd be riding the bus by herself, and that her teacher would meet her, and she'd get to meet new friends, etc. I didn't really believe that it would be enough, though, and I had visions of her crying the whole way and crying all day at school, and the school calling me because she wouldn't settle down. Okay, I was a basket case. I wanted to follow the bus, or at least show up at the school when the bus would arrive and make sure she was okay (Nate thought I was crazy). But when it finally came down to it, she happily ran across the lawn, climbed on, and drove away with a big smile. So what was I worried about?
