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.

Except for the dust, I’d say it belonged to a kid who played it too loudly.
I cleaned out my house a couple of years ago and got rid of quite a few things that I probably could have sold, but didn’t want to bother.
Very true lol!
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.
