I was talking to this guy named Chris - he told me a story I've heard all too many times before...
Basically he loves to play guitar with his mates, but his big problem is if there isn't a page of chords in front of him, he's totally lost.
He kind of gets by, bit by bit, by watching the best player in their group, but inevitably, he's always a strum or two behind the group, because it takes him that long to recognize what new chord they've moved onto.
Usually the others are pretty good about it, but whenever other people are watching them play, Chris gets pretty self-conscious.
