An Embarrassing Experience──Draft 1.

Last Friday, I got up a little late , so I went to school immediately. On the way to school.
I went to buy breakfast at 7-11.I didn't saw my wallet very clear. I took the food and drink.
They cost me 50 dollars. But I didn't know I took only 10 dollars.
I gave 10 dollars to the clerk. And he looked at me for a moment.
Oh my god ! I was very embarrassed. Luckily I found 50 dollars in my bag.
So now when I go shopping , I will check my wallet.
