I was writing a short chanting song to my sister to help her kids learn some new vocabulary:
"Once upon a time , there's a little kitty whose name's Hello Kitty, falling in love with Japanese Melody".
She asked me why story always begins with "once upon a time" but there is more than one stories she can find in the story. Then, I told her that you should count how many stories you can find out, and change "once" to twice, thrice...
My question is that, if we replace "once" with "twice" or "some number adverbs", will it make audience feel tedious or bored because they have been told how many stories would likely to happen?
