I learned this in the mental hospital last year, with like the same exact looking classical guitar. There was a patient going thru a psychotic break and a fentanyl cold-turkey detox. One of the nurses told me he sat up in bed and looked up me playing thru the doorways and hallway of my dorm and his dorm. When she told me, I wanted to speak to him and tell him the song I was playing, because it wasn't my own. But maybe an hour later, he tossed a medication cup at an orderly, got subdued and sent to a psychotic ward of the hospital. Haven't seen him since or ever
