fighting with my cousin over a toy

That day I went to my cousin's house and play with him and we both like the same toy but we just get one there so we got to have a rotation , but I let my cousin play frist but it is almost lunch time . So we have our lunch frist then we keep playing the toy but I finish my lunch so i got to play frist but my cousin is gellous so he hit me then I hit him back and punch him very hard .When he wants to hit me back instead of punching him I kick him back by using my feet . But later that day our parents knew this and tell us to say sorry to each other and not to fight again. In this time's fighting I learn that we can not use fighting to slove problem we can talk and make a dision and not to fight because fighting cause to get injure and hurt so fighting is not good. Then don't fight remember fighting is the worst thing to slove problem!
