Science Troubles

I was laughing in my science classroom...like, a little giggle...For a specific reason, the teacher kicked me out.  I felt that this was unfair because I expected the teacher to be as nice as possible.  Other people were laughing too, during the end of class.  I was the only one who got kicked out.  I feel very disappointed because the teacher told me I wasn't funny.  I admit...I was trying to be funny.  But now, I regret this.  I admit I might have hurt my teacher's feelings by laughing.  I was laughing during the lesson and he probably thought I was laughing at him.  I should probably take deep breaths in class to control my laughter.  I guess I should also apologize and tell him that I feel really bad for laughing in your class and I'm sorry...I will never do that again.  I was trying to just have fun without an aide in the classroom...and now it feels like it's all messed up.   My friend told me that really, all I have to do is apologize.  Then it won't be all messed up again.  That seems easy to do.
