Getting back to playing guitar

I used to play guitar often. It has been more than three years since the last time I played regularly (if you can call playing every now and then regularly). I have been looking forward to play again (did it yesterday for my daughter), but musical instruments are the worse of friends. They really let you know that you have not been paying enough attention to them. They let you know right away, and they don't stop reminding you out loud. You can hear it in every note!)
