Yeah, I bet you're getting pretty good, dude. What kind of guitar do you have anyways? I have a friend who's been playing about...ahhh...I think a year and a half to two years, but she has the biggest inferiority complex where guitar is concerned, so she hasn't improved but so much and is terrified to improv with her scales. I'm sure you're way better, because you seem pretty confident. Come to think of it, my cousin is the same way. He's terrified of making mistakes in front of people. One of those guys who'd do anything you tell him because he craves acceptance so desperately, you know? Anyhow, keep it up, dog, and memorize what they told you, and be confident about the scales, you don't want to start sucking just because you're afraid to suck.
