An embarrassing experience - Draft one

I had an embarrasing experience when I was 14. One day, on my way to the cram school, I saw a man and a baby. They are similar to my teacher and his

child, so I called them very loudly on the street. But after they turned to me, I

found he was not my teacher. After that, I rode the bicycle very fast. It was really embarrassing, because there were also some people walking on that street. Now I don't call people loudly on the road, unless I am very sure who he

is. I don't want to make the same mistake again.
