An Embarrassing Experience-Draft Two

I had ever met an embarrassing experience that I would not forget. It made me so shy.
One day, my friend, Sherry and I went to a department store to buy some stationery.I was choosing the things what I want. Suddenly, she found she only have 20 dollars, she said "I only have 20 dollars , can you lend me ?" "Of course, we are the best friend, I still should enough money." said I . I thought I had enough money to lend her, and therefore, I didn't check my wallet whether I had enough money or not. When we were at the sales counter, I found I only had about 50 dollars. I scared , I cannot say any words. I put down all products which I wanted to buy in a hurry. All of the people looked at me, I felt so embarrassed and bad. The day must was not my day.
