Embarrassing Moment at the Supermarket

In my whole life, I have lived lots of embarrassing moments, but I think the most shameful one happened when I was six years old. I went to the supermarket with my mum to buy some groceries for the week. At the beginning, nothing went wrong, but, when we were at the cash register, my mum realized that we had forgotten the milk, so I had to get back and grab it. When I went again to the cash register, I put the milk into the cart and I hugged a woman who seemed to be my mum. Suddenly, she started laughing at me and I realized she was not her. I had never felt so embarrassed in all my life!
