Matthew teaches violin

Matthew informed me today that he teaches lessons between Best Buy and the McDonald's Play Area. He forgot to bring his violin the last time he taught. He has seven students and teaches only violin, no guitar students. I asked him what days he teaches. "Vi-o-lin. How spell violin?" (Some days when I ask him how many lessons he has, he needs to refer to his calendar on his cell phone. He tells me to wait a minute while he checks.)
