Guitar Hero

All this time I thought that Diego-san's forlorn look whenever I practice my guitar was due to his displeasure with the noise/music he was forced to endure. Recently I bought a second guitar so I could have one with nylon strings as well as one with steel strings. Since I only have one guitar case I have to leave the second guitar sitting out. Yesterday I was awoken by the sound of Diego-san plucking the strings. Maybe his displeasure isn't with my performances, but rather him feeling left out and wanting to contribute....
