Open class day

Today it was open class day for hobo ( lower degree till highest) and my brother in law had to play his part. From long time ago he had a desire to master the hobo , which isn't an easy instrument. In between his busy job and household he finds some time and does it well. It was a pleasure to hear the performance of all the students.
On the photo he's standing with his teacher who's just giving the last advice before the performance . Although i had another pic , while performing , but this is the strongest one , the relation between tutor and student. I'm stil acting as in analog days , which means just taking a few pics.
