Babies do not know skills such as flattering, fawning. They always "believe and depend". It reminds adults of innocence in them. In the past, when a baby was crying, no matter whose baby he/she was, people dandled and took up him/her in their arms. Even strangers, they felt that they were also responsible for the baby when they heard him/her crying. The musician and movie maker says that there was the starting point of safe living there.
