Life is a Musical

Keith and I recently attended a Parent-Teacher Conference to discuss Samantha's progress in school. Sam's teacher had nothing but accolades and repeatedly praised Sam's cheerful, sunny disposition. But teacher did have one thing Sam could work on: less singing. Apparently Sam sings while working at her desk. This is rather unobtrusive and can be overlooked as long as Sam sings low but when she gets to the chorus she has a tendency to swell. Sam's teacher said she will often let Sam continue singing until the children around her show signs of being disturbed and then she will simply tap Sam on the shoulder, bringing her back to reality. Teacher admitted that Sam is doing this unconsciously because she blushes upon interruption and is quick to apologize. It is also worth mentioning that many of Sam's songs are personal compositions because she will actually sing about what she's working on at her desk (insect life-cycle, fire safety, phonic coding, just to name a few). I blame Zac Efron.

So, as a parent, how do I help Sam break this harmonious habit? More important, why should I?
