Don't you love it when you get questions such as the following from parents:
"So, how many lessons will my daughter need to learn to play?"
or (this was someone who had never played an instrument before)
"My daughter needs to get grade 4 by the end of the year for XXX award. Will 30 minutes every fortnight be ok as she's got a lot of schoolwork this year?"
Then there was the following:
"Do you give free lessons?" (seriously!)
