Calluses. Yay or Nay?

Who likes calluses?  Hard pieces of skin on your hands, like a shell of protection. I alway pick them off though. I don't know if people think they're cool, or they're gross. I think they're sorta cool. I need to grow calluses on my fingers. I need one on the side or my right thumb, and then on the topside my left fingers. Cause I'm just so cool and I okay instruments. I play the Ukulele, and now I'm learning to play the Banjo and Guitar. I need a teacher.. But anyways, calluses. Yay or Nay?
