With all our wonderful ideas in play David decided that he didn't want to practice. He would practice if we forced him to but there was no internal motivation. With homeschool we've decided not to force our kids to do anything they don't really want to do (we may amend this policy later). But we decided to hold out until the first concert before we decide to continue the lessons or not.
Well, David had an enjoyable time at the concert and with the extra lessons too. But he still won't practice so this may be his last piano recital. Of course, we'll probably explore this option at a later time.
