tsk tsk tsk...

guitarists have short fingernails on their fretting hand, and if they choose for finger picking long fingernails on that hand...

being right handed, I strum/pick with my right hand, and that's where my long fingernails reside...my left hand, for fretting, has the nails cut to the quick...

sorry, but your play on words was wrong (hence it went right over my head)
