Very expensive

  She said ” Your painting classes are very expensive. ”

I am used to these kind of words. I asked her, ” Why you want to learn art? ”

” It’s my childhood dream. ” she said

”  How much do your shoes cost? ” I asked her.

She got confused. She had no clue why I asked that question.

But she replied, ” Five hundred dollars. ”

” How much are you paying for each of my classes? ” I asked her.

” Thirty dollars. ” she said.

” Lady…You bought the shoes for five hundred dollars. After few months you will throw them away. You are paying only thirty dollars for my class. Whatever you will learn in my classes, that will be with you till your last day on earth, ” I paused for a moment and asked her ”…Now tell me …which is expensive ”
