What is an echo?
give me an short answer

Echo when the sound reflects back

the repetition of sound that results as a reflection from a surface.

There was one morning, the sun was up, and it was a nice day outside and it was the first day of school. I put on my shoos and walked out of the door. I finally got to school and went to class. the class was well lit up and had the best scenery and there he was, my first friend it the whole school. As I looked at him he smiled and I knew we were going to be good friends. I finally decided to approach him and we started to talk. After our long conversation that lasted the whole class I realized I didn't take any notes. I left the class and headed to my second period. I open the door and then he walks in behind me. We spend the next 2 periods together and had a good time. we went to lunch and that's when it all happened. After we sit at our desks he tells me he is going to start a food fight. I beg him not to but he dose anyway. That's when it started he yelled "FOOD FIGHT" and I got mad at him. He did this everyday until that Friday when I asked him if he ever wanted to be friends in the first place. He said no and that is when I made even better friends than him. I personally think this was a good experience and it taught me that some of your friends aren't the best people.
