I am continually amazed at the number of people who call me for piano lessons. Two of my students are dropping after Christmas because of monetary reasons, but I already have 4 kids on my waiting list. Additionally, tonight I had a dad call me (someone I didn't know) wanting 2-3 of his kids to start. Onto my list he goes. He told me that one of my student's (well, technically 3 of my students' since they're siblings) parents had HIGHLY recommended me and that I was an excellent teacher. It's nice to be appreciated. Word of mouth really is the best form of publicity.
