Swimming school

Yesterday was the first day for Kana to go to the swimming school and she enjoyed it very much.  There were first time trial lessons for free last month and Kana did them with joy. Since then, somehow she didn't say she would like to join it.  I convinced her that how it's important to be able to swim and she must swim at her school.  The other day, suddenly she answered "Yes".  I hurried to sign up for it before changing her mind.
