He knew how the audition was going to affect their lives for the next ten weeks as she slowly lost her mind from nerves and the strain of trying to scrounge precious practice time from an already jam-packed life. No matter how much time poor Sam gave her, it would never be quite enough, because what she actually needed was for him and the kids to just temporarily not exist. She needed to slip into another dimension where she was a single, childless person. Just between now and the audition. She needed to go to a mountain chalet (somewhere with good acoustics) and live and breathe nothing but music. Go for walks. Meditate. Eat well. Do all those positive-visualization exercises young musicians did these days. She had an awful suspicion that if she were to do this in reality, she might not even miss Sam and the children that much, or if she did miss them, it would be quite bearable.
