,It turns out that two months of quarantine doesn't magically make the tone deaf wannabe musicians upstairs any more talented. One of them is still banging around on the piano while the other alternated between playing the recorder or singing, two skills they have never possessed and never will never possess.
Apart from a possible career recording shred videos for Youtube in 2012, I can't imagine what benefit their continued abuse of instruments does. It doesn't even seem to relax them or assist them in having a good time. They seem to be as frustrated by their incompetence as everyone else in the building. But that won't stop them from singing the same four note progression, or continuing to flatly exhale to the rhythm of Hot Crossed Buns.
For revenge purposes, I've been looking at bagpipes online but they are prohibitively expensive. As they should be.
