In my class every1 laugh when some1 says something wrong. People are scared to pull their hands up and say the answer to the teacher. I am not afraid even if I'm wrong. I always pull up my hand even tho im wrong most of the times but its kinda annoying that everyone in the class laugh.. Why is it like this?
