Wednesday, I jumped on the train to head home after a very full day at work and found my daughter leading a music class with my son, the nanny, and the other boy in the nanny share. They were all playing instruments as my daughter sang her song. My son then started singing nonsense words and beating his drum to his own rhythm. Though somewhat exhausted from the day, I joined in on another drum; we have lots of drums. After the nanny and other child left, I continued playing instruments with my kids for quite a while. As hard as noise is after a day of work, they were having so much fun, I just had to join in.
