which is important life or play?

I bring my doughter to supermarket.When the way to skateboard (游龙板) ，she stop at roller skates show and want to try . I want to introduce her to skateboard , so I said :"maybe it is dangerous for you,when you falled to grand,you could get hurt.more seriously,you lose blood ". Daughter hesitate for a moment, decided to leave . At that monent ,I feel guilty.so I tried to converse it . I persuade her :"ok,let us try".but she refused.I got ashame to myself. so I encourage her"not very dangeous if you learn to control it . there are many girls as your age can play well.It is very interesting." but ,she had decided to give up this ,she said me seriously ,the attitude like teacher :"which is importtant? life or play "
