Sock monsters, picks, and capos

In my quest to learn guitar, I broke down and took my Free To a Good Home guitar in to have it set up to lower the action. If it was lowered, it wasn't by much, but the fret board is much cleaner and they switched it to light Martin Silk & Steel strings. So daily practice has resumed and calouses are coming along nicely. Chords that I can play reasonably well now are G,D,E,C,A,Em,Am,Dm,B7. During my self studies, I have been making use of YouTube, and I ran across this very informative post on how to use a Capo, which warns against the Sock monster. Apparently Sock monsters play guitar and not only take one of your socks, but your picks and capos as well. Watch out people!
