On the days that Z takes the bus Az and I walk down to meet the bus. The routine is that I carry Az down, because it takes Az a bit too long to meander down while the bus is waiting. On the walk back up, however, Az marches back up the whole way on her own. There is no meandering or stopping to look at things most of the time; she is on a mission. That hill has exhausted much longer legs than hers so I'm always a little proud of her for making it up without requesting to be picked up. The reward for her efforts is usually getting to play outside with her brother before we all head in.
