Hi Steve,
I wish I had an answer for you. I had this problem with a couple of kids and basically came to the conclusion that I'm just not that good with teens because they had a great time the week I was sick and my husband trained them instead of me.
After a few clients like this where it was torture for them and me, I made a decision to stick to what I'm good at and not take on any more kids.
Probably not a very helpful answer...
One did perk up a little when I asked him to make a CD for the sessions. :P
I hope it gets better!
Salut,
Kaisa
