I saw it on my way into town, somebody put out a casio WK-3000 piano out on the curb for free, with the stand power cord and even manual. The craziest part is its fully functional. Not a darn thing wrong with it 'cept some dust. Now I have to learn piano.
It could also be a new year’s resolution piano or something. Someone thought “I’m going to buy a piano and learn to play it” and it sat around taking up space without them learning it. They finally decided to just get rid of it.
