YES! She went!

Yup...Okaasan overcome all the silliness (for this week anyway) and went to hula dance class.
Yujiro's letter worked...she ate the bits of lunch on the kitchen table, got washed and dressed and WENT to the class.

Great. She enjoys it. She needs the exercise. She needs the social interaction with classmates.

In fact she then stayed out for hours and ate something downtown. Came home about 6.30 pm.
Ate dinner with Yujiro, and was pretty tired after a big day out.

Yujiro didn't ask her directly about hula and later he called the friendly classmate to check that she had actually gone.
Not only had she gone. But she'd been ther first to arrive and greeted everyone!

So that's alright then. For now.
