She plays the guitar just off key because you promised that it wouldn't hurt to mess up once in a little while. Strangely enough, you have a hard time keeping promises but you did warn her from the start. You warned her gently with a slight smile as waves of precaution and worry resided in her eyes, you taught her the art of gently shrugging it off.  She plays the instrument  just like you taught her to before you parted ways with sights that were so familiar. Familiarity is a hand-made jacket that you shrugged off without a second thought, without a second glance. While she had just learnt the act of playing along.
