That's right - I said you need more practice. Frankly, I've about had it with your lousy attitude about practice...
Again, as I suggested in my remarks about the practice section of Gentle Annie, you could approach this in a few different ways.
1. Play the same thing along with me
2. Play the chords along with me, but not necessarily the melody (and I mean play your sub-basses too - because you always want to be practicing getting those to be second nature - muscle memory, muscle memory, muscle memory).
3. Look for some harmonies to what I'm playing. Or maybe some little melodic answers to me.
