On the other side of the street
When I was in school, I used to have a very embarrassing nickname. One day, I was at a bus stop in the city's downtown when I saw some classmates turning the corner on the other side of the street. The bus stop was crowded and I tried to hide myself behind those people. But it wasn't enough. They saw me and started to call me by my nickname. It was very embarrassing!
• Embarrassing instead of embarassing.
• You want to use at school when you refer to one specific occasion. When it comes to something you would repeatedly do for a given time period ("Son, wake up! You need to go to school!"), it would be better if you used in.
