Someone lent me a guitar - how do I learn classical guitar

I had a splinter in my left hand for a couple of weeks so I couldn't bend my fingers.  I tried to keep practicing right hand patterns but now my finger healed, I suspect I forgot everything I learned about music so far,

How can my brain forget so much so fast?

Had a look at some more guitars.

Choice 1. Save up for cordoba.  It seems a good fit for my hands.

Choice 2. Suzuki parlor that is in need of major repair, very badly bashed up.
