I was just remembering...my niece was 16 when my brother married her mom. They would come up to visit, and my niece would just sit around. No, she didn't want to go for a walk with us, she was tired. My brother said she was like that at home, never wanted to go biking with them, etc. She wasn't overweight or sickly, just never had any energy. They thought she had LTS (Lazy Teenager Syndrome). Who'd blame them?

Turns out she had Myotonic Dystrophy. She wasn't diagnosed until she had her second baby (who was born with it and nearly died). We all get some points for not KNOWING there was something "wrong" with her, but I still remember how I felt...that she wouldn't be so tired all the time if she'd just DO something, get some exercise.

I'll always remember that poor child on my sofa saying, "I'm sorry, I just can't". And how frustrated and yes, judgmental we all felt, essentially telling her she could if she'd just try.
