This is for my physical education class. we are focusing on communication. for extra credit i have to get an opinion other than my own. the question is below : )

communication is the act of sending and receiving messages. sometimes messages are communicated verbally, with words, or nonverbaly, with body language. when communication is effective, the intended message is received. when communication is ineffective, messages are unclear. describe a time when you had difficulty communicating a message. why was the intended message not received properly?
