Have you ever felt really embarrassed?

Of course, everybody has felt embarrassed. I remember on time when I was a child and went to school. We had to go to library for read books. We need to take out shoes before entry inside of library. When I took my shoes out, then I and my classmate saw my hose had broken a hole, they laughed at me. So, I had felt embarrassed at that time. Now, I will check the hose, which has broken, before I wear.
